This window type is similar to 'screen cu -l /dev/ttya'. Read and write access is required on the device node, an exclusive open is attempted on the node to mark the connection line as busy. An optional parameter is allowed consisting of a comma separated list of flags in the notation used by stty(1): 1200,9600,19200 - First parameter is the. I'm having the exact same issue with the same symptoms (and have tried the same steps to 'fix' the problem). Did you find any resolution? The DigiCDC CDCLED program works with the Arduino Serial Monitor with a Mac OS X 10.8 machine I have sitting around, but does not work on my 10.11.3 machine (although I have no issues programming it). Hi there, I am making a project, where I am trying to use processing and my Arduino together. I am fairly new in both of the programs. I haven't had problems with the Arduino program saying that my serial port was busy, until I started using Processing.
Mac OS X includes a great terminal editor, but among the handful of alternatives is one that easily rises above them all. ITerm2 is our pick for the best terminal emulator for Mac OS X thanks to. So type Control-A followed by Control- to exit your screen session. If you fail to do this and exit a Terminal session, you'll leave the screen session alive and the serial resource unavailable until you kill the screen session manually. Man screen will show you further commands to send to a screen session.

Can you not just save all that as terminal profile and then double click it, or select it from the Terminal dock menu? No applescript involved.

I use the following keyspan.term (string-style plist for readability): Note that you can control the terminal baud rate and other characteristics with the last argument (see the WINDOW TYPES section of screen(1)).
Or just use QuickTerm
Hello
I am not a programmer. What shall I do when I've setted the port of QuickTerm, and came back to the window 'RS-232 Terminal'.
I clicked on 'Connect'. It probably connected but the window is empty, I cannot type anything in it, and anyway I don't know what to type.
I want to use it for our French 'minitel'. I think it is V33, but not sure.
I use a laptop and MacOs 10.4.9.
My modem is inside :

Is X11 necessary ? I am not keen on the terminal, so could you give basic explanations.
Thank you.
No need to shell out for Keyspan's admittedly very good drivers. Many USB-serial adapters use the same chip, Prolific Industries' PL-2303 controller. Prolific's own Mac OS X driver is currently not very good; you can't send a break signal via screen in Terminal, for example. However, there's an open-source driver that works better.

I use this with an unbranded PL-2303-equipped adapter bought from eBay for six of our English pounds, compared to thirty-odd for a Keyspan device, and it talks perfectly to my Cisco routers. I haven't tried talking to PDAs or GPS devices though.
'Shell' out. See what I did there? Heh - oh dear.
You can also use C-Kermit 8.0. Unfortunately a binary is not available, we must compile it by ourselves, but it's really easy, as Mac OS X is supported.
Download the source at the following address:
ftp://kermit.columbia.edu/kermit/archives/cku211.zip
Copy it in a folder, then, using terminal:
% cd <the folder you copied it in>
% unzip -a cku211.zip
% make macosx103
% sudo make install
it will compile and install Kermit in the folder /usr/local/bin/kermit; the binary is called wermit.
It's ready! to launch it:
% /usr/local/bin/kermit/wermit
and here it is:

I last used C-Kermit when Jaguar was out. It worked great. PowerPC binaries for 10.3 and earlier can be found here: http://www.columbia.edu/kermit/ck80binaries.html#apple
Wow! Kermit - I haven't used that for at least a decade, but I seem to remember that it was very good.. must give it a try..
Anyway, that aside, for those who like minicom, Jeffrey Frey has done a Mac port which can be found at the bottome of his page here:
http://turin.nss.udel.edu/programming/
also the awesome thing about kermit which i've been using recently for a few years is that it lets you send files via xmodem (useful when ur cisco gear pukes on itself), and also kermit is scriptable (useful when you have 50+ apc power strips you have to configure the same way, enter non-interactive script).
I'm not saying I'd recommend it, but you could also use tip, 'man tip' for more info.
osx unfortunately doesn't come with tip . i was disappointed quite a bit when I found out
There are quite a few installer packages for minicom that remove the need for fink or darwin(er. mac)ports.

This is an excellent solution (I've been a regular, frustrated, user of ZTERM). I am, however, unable to configure the serial port settings (I routinely connect to a serial device running 38400/n/8/1) I've tried every combination I can imagine with stty to set the port before starting screen and it is still always stuck at 9600 baud.
Update: I found on Apple's discussions board the following, which works:
screen -U /dev/tty.KeySerial1 38400
Adjust the script accordingly and it works perfectly!
Here is an addition I made to select the serial port and the baud rate: screen -U /dev/tty.KeySerial1 38400
Adjust the script accordingly and it works perfectly!
set baudList to {1200, 2400, 4800, 4800, 9600, 19200, 38400, 57600, 115200, 230400}
set baudRate to (choose from list baudList default items {38400})
tell application 'Terminal'
set serialDevices to (do shell script 'ls /dev/cu*')
set theDeviceList to (paragraphs of serialDevices) as list
set theDevice to (choose from list theDeviceList)
do script 'screen ' & theDevice & ' ' & baudRate
display dialog 'To quit you terminal session type then '
end tell
the second to last line should have been:
display dialog 'To quit you terminal session type <ctrl-a> then <ctrl->'
display dialog 'To quit you terminal session type <ctrl-a> then <ctrl->'
The second to last should have read:
thanks for all your help, especially bboy for the cheaper cable, and wcontello for the AppleScript.
I am currently taking 2 classes that use HyperTerminal, a Cisco test prep class and a basic Telecommunications classes. I've wanted to use my MacBook Pro to use something HyperTerminal related. I have a beta of Windows 7 in Boot Camp and VMWare, and MS got rid of HyperTerminal in Vista. And of course no Mac (except for Xserves) have a serial port.

You wrote: 'type Control-A followed by Control- to exit your screen session. If you fail to do this and exit a Terminal session, you'll leave the screen session alive and the serial resource unavailable until you kill the screen session manually.'
OK, I boo-booed. Now how can I kill the screen session manually?
(I wish I knew Unix better.)

Look for a process called 'SCREEN' using ps. Here's the output of my Terminal: OK, I boo-booed. Now how can I kill the screen session manually?
(I wish I knew Unix better.)
--Gil
Kill the process associated with SCREEN (i.e. '
kill -TERM 327
'), and the SCREEN will go away. You can also reattach to a detached screen by running '
screen -rD

Another solution would be using the ZOC Terminal application. I used zterm initially and found it horrible too. ZOC is a lot more modern in every regard and works with a serial/usb adapter.

If you want to use screen as an terminal, but don't want it to go into the background when the window dies, you will need to turn off auto-detach.
To do this, edit ~/.screenrc (it probably won't exist) and add the following line:
autodetach off
The next time you start screen, if you kill the window you will kill the session.

How about simply 'cu -l /dev/whatever -s 19200' and that's all it takes.
Thanks! Working great w/an IOGEAR GU232A USB to Serial adapter which uses the PL2303 chip set.
This is a fantastic thread. Saved me from using Zterm. One problem though. I'd like to be able to scroll up past the top to show more than one page of data. Anyone figure out a way to do that?
Never mind. A little googling found the answer I was looking for. To turn on the scrollback buffer for SCREEN you have to add one more line to ~/.screenrc More info here: http://stackoverflow.com/questions/1039442/mac-os-x-terminal-apps-buffer-and-screen-command
since people are still posting to this 4 year old thread, I think it's useful to point out that iTerm - http://iterm.sourceforge.net/ - is a cocoa terminal editor that is up to date and under continued development (and that's not to mention the Terminal application packaged with os X).

Introduction: Tiny Linux Server - VoCore2 - Getting Started
The VoCore2 Ultimate is an impressive piece of miniaturization and is worth considering for embedded control applications.
This tutorial will help you learn how to:
- configure the device's settings,
- add secure internet access, and
- control the on-board LED.
I bought the Ultimate version (with enclosure and standard connections) since it seemed like a quick way to get started. For embedded control, the PCB is also available and is about the size of a postage stamp.
Supplies:
- VoCore2 Ultimate (https://vocore.io)
- USB Cable (USB to USB-mini)
Tools
To configure a VoCore2 using this tutorial, you will need to use the vi text editor and a serial emulator. If you are not familiar with these, there are links in the tutorial which will provide assistance.
Step 1: Power-up the VoCore2
Connect a USB adapter cable between your computer and the VoCore2. The mini-USB connection on the VoCore should be used for this.
Step 2: Connect to the Luci Config App
The config application runs on the VoCore2 and you can get to it through your browser.
- From you host computer/laptop, connect to the device's wifi network (SSID: VoCore2-…)
- In your browser go to: http://192.168.61.1/
- You should see a web page asking for credentials.
- Enter ID: root
- Enter Password: vocore
- You should be in the OpenWrt system config app now.
You can also enter configuration commands using the VoCore2 console, which we will do later.
Step 3: Load Latest Firmware
Use the Luci Navigation to go to:
System > Backup / Flash Firmware
- Get latest download from https://vocore.io/v2u.html Section titled: 'Upgrade VoCore2 Firmware'. As of 2019-Nov-03, the latest version is shown in the screenshot above.
- Save the file to your computer.
- Use the Luci interface to select it.
- Press the 'Flash Image' button to load it into your VoCore2.
Mac Terminal Serial Emulator Screen Resource Busy Number
Step 4: Set System Time
- After loading the new firmware, wait a few minutes before reconnecting to the VoCore's WiFi network (SSID: VoCore2-…)
- In browser go to: http://192.168.61.1/
- Go to Menu: System > System
- Skip down to Timezone and select your timezone
- Go back up and press 'Sync with browser' button
- Leave the rest of the options as default
- Press 'Save & Apply' button
Step 5: Add Internet Access
The device's default mode is to run as a network Access Point (AP). You can connect to the device by mini-usb, WiFi, or Ethernet, but the device will have no Internet access. To add Internet access, follow the instructions below which will enable STA (network Station) mode to operate. (After adding STA mode, the device will still operate as an AP and the Luci configuration app will still be available.)
The following steps will add Internet Access.
Step 6: Connect to the VoCore Console
From PC
- Open Control Panel > Device Manager > Ports, look for 'USB Serial Device', remember COM port number
- Use Serial Terminal Emulator (Example: Putty)
- Set up connection params: Com_Port_Number, 115200 bps, 8 data bits,1 stop bit, no parity, no flow control
- Once connected, press Enter to get Linux shell prompt
From Mac
Open Mac's Terminal app and run the following command to find Serial Port info.
The response looks like:
/dev/cu.usbmodem6A68DE4F34311
Enter your actual response within the next command, to start the terminal emulator.
That will open the Screen terminal emulator. You can now press Enter to get the Linux shell prompt.
Step 7: Add Station (STA) Mode
Background
This section uses uci commands which help configure the OpenWrt operating system. (As an alternative, you can also edit the associated OS files directly.)
This section is derived from: https://vocore.io/v2u.html. I abridged the instructions for clarity. In order to avoid errors with 'uci commit':
- I put all uci parameter values in quotations.
- I omitted commands for parameters that are already set in their respective /etc/config files.
I also added a few extra commands to configure the new Access Point's WiFi network, including:
- appropriate frequencies to match your country's regulations, and
- secure login credentials.
Instructions
1. Connect to device's console through its microUSB (see prior sections)
2. Run the following commands in the console.
3. Configure boot-up script so that if your existing WiFi network is down, you can still connect to VoCore2.
Use the vi editor (included with OpenWrt) to insert the following code into /etc/rc.local
4. Setup firewall to enable access internet through your hotspot.
5. Add additional parameters to configure appropriate WiFI radio frequencies based on your country such as Canada or US, respectively:
More country codes at: https://www.arubanetworks.com/techdocs/InstantWen..
6. Set Access Point Login Credentials and Encryption
The device comes without a password on its WiFi access point (SSID: VoCore2…), so add one here.
Note that psk2 includes WPA2
7. Update Wirelesss by running:
or by running
or if it's still not behaving, by rebooting device:
which will of course take longer than reload or restart.
8. Wait 30-60 seconds for the device to enter AP+STA mode.
9. Connect your host computer to WiFi, picking the network called VoCore2..
10. Confirm Internet connection by running:
The response should show something like:
If you're having troubles getting network connections to work, use the previously mentioned reboot command. If that doesn't work, disconnect the USB cable, wait 30 seconds, reconnect the cable. You can also check the /sys/config/ folder to ensure that the commands (above) configured their associated files correctly.
Step 8: Controlling the Onboard Red LED
![Resource Resource](/uploads/1/1/9/8/119845495/297393192.jpg)
To control the onboard LED which flashes red during WiFi activity, I found that the following approach works:
Un-trigger LED in Luci App
From the Luci app:
- Use the menu to navigate to System > LED Configuration.
- Set the trigger to 'none'.
- Press Save and Apply
Presumably the default setting would make this the state after boot-up, but I didn't test that.
Control LED with Console Commands
To turn the LED on:
To turn the LED off:
Caution
Controlling the LED this way may conflict with OpenWrt's use of the LED, but worked during my tests.
A better way of controlling GPIO is to use the export command, however this command does not work for GPIO44 (which controls the LED, based on schematics and router manual screenshots shown above). So the Operating System is likely, still holding on to this LED, despite Luci setting.
