Mac's and serial TTY's. Mac's are excellent tools for accessing serial device TTY ports (to console into PBX's, switches, and routers). You just need a serial to USB adapter, the right driver, and some Terminal software. You can use screen, although Minicom (or a GUI program) offer more features and functionality. MagerValp wrote this C=64 Terminal for Windows/MAC. The official website for CGTerm 1.6 is here. Development has ceased for this project, so if there’s any bugs, you’ll have to wait for the newest CBMTerm by Six. Open source – runs on Windows, MacOS X, and unix compatibles. Full C64 screen and keyboard emulation.

Raspberry Pi and the USB to TTL Serial Cable on Mac (unfinished)I took it to heart when said to durring. So I documented my whole process, what went right and what went wrong.This document is unfinished and is not a complete tutorialThe primary way to interact with a Raspberry Pi is to use WiFi and SSH. The problem with this is that the WiFi on the Pi needs to be configured and in order to do that you'll need a monitor. I've tried to edit the wpasupplicant.conf by using the SD card's file system. I achieved this with minimal success the problem with this is that you still need to get the IP address of the Pi, even if it's connected.Alas, there's another way!
Using a wire referred to as the '.Note: The Raspberry Pi has a power cable, you know the one that plugs into the wall. It is important to note that the Raspberry Pi has another alternative way to be powered. It's the farthest most pin from the board on the corner is a 5 volt input not output, as I misread several tutorials. The cable we're using has a red wire that powers the Pi. This being said you should only use one methods of powering the Pi.DO NOT USE THE RED WIRE AND POWER ADAPTOR AT THE SAME TIME! Wiring it up!red power, black ground, white RX into USB port, and green TX out of the USB portNote: I originally had the white and green wires reversed because of this image from a adafruit tutorial, which is why I had the. Special thanks to.
Installing the PL2303 USB to Serial DriverBelow are links for the two options for getting the PL2303 driver to work on OSX Mavericks. I've tried NoZap in the past with no luck.Note: It seams you can't have two of the same drivers installed. If you run the NoZap.app file again it will uninstall it, then close terminal and unplug / plug in the Pi.I'm going to use try using the osx-pl2303.kext for the rest of this tutorial. Making the SSH ConnectionWe're gonna use the screen command, which is a terminal emulator. We have to point to the usb port and pass in 115200 (Speed Baud rate).Enter screen/cu. Then press tabit will show you a couple of options for drivers. When the usb wire is unplugged it shows only a couple of Bluetooth drivers, but when it's plugged in it shows the PL2303 driver and the number 00001004.
Screen /dev/cu.PL234 115200this later changes for me to, (remember to tab through options!) screen /dev/cu.PL2303-000013FA 115200THIS IS WHERE I GET AN ERRORErrors / Results. It just hangs with a empty terminal screen. It errors / flashes Cannot open line '/dev/cu.PL2303-000013FA' for R/W: Resource busy and then lands on Sorry, could not find a PTY. Then I get the command line back with a printed screen is terminating statement.
If I run it with sudo ie sudo screen /dev/cu.PL2303-000013FA 115200 I get a completly different error /dev/cu.PL2303-000013FA: ioctl TIOCEXCL failed: Resource busy, then the blank terminal screen.Theories. A connection has been made. It's just I'm not able to see the command line, or write commands. I believe this might be an issue with the setup on the Pi itself. I only get this error (so far) after I've ran the command and gotten a blank screen in one terminal session. I believe that it can't make the same connection twice, hence why it's busy.Questions. What's the difference between screen /dev/tty.PL2303-000013FA 115200 and screen /dev/cu.PL2303-000013FA 115200?Actionable.
I'm running sudo apt-get upgrade on the Pi now. (Taking forever). Reinstall raspbian. Futz with the /bin/inittab file on the PiInittab & cmdline.txt sudo nano /etc/inittabHere's my file and my file.Like a gift from the gods someone made this, which checks both cmdline.txt and inittab.Using the tool I'm getting an, follow that issue to see how I got the tool to work.After all this, I run the screen command again to continue to get a blank terminal window or resource busy.
Where I left off. This.
Send an email to the creator of rpi-serial-console. Stackexchange questionResources. (black white green). (black white green). (black white green).
I figured it out somehow. The serial cable has to be connected Black-White-Green.I used the installer hereAfter reboot you should be able to connect by calling ls -l /dev/tty., finding the right device name, and using screen /dev/tty.PL2303-etc. 115200. When you get the blank screen, press enter to get the login.I'm using Yosemite (10.10), but it should probably work on 10.9.If you get that Sorry, could not find a PTY error, call screen -X kill to kill the screen service and it should then work for you.
RequirementsYou have assembled your or your, installed the appropriate drivers, and flashed the OS image (formerly called firmware). Steps to Set Up a Serial Terminal. Launch Spotlight by pressing Cmd + Space.
Type terminal. Select the Terminal app. In the Terminal window, enter the command:ls /dev/cu.usbserial-. In the list of connected devices, look for a device that contains cu.usbserial.
In the example above, the device name is /dev/cu.usbserial-A402YSYU. Note: If your device is not in the list, verify that your board is powered on and connected to your system. Select the appropriate link below:. Connect to the USB serial device using the Terminal screen utility by entering the command:screen /dev/xx.usbserial-XXXXXXXX 115200 –Lwhere /dev/xx.usbserial-XXXXXXXX is replaced by your device unique name.
Using the example above, the command would be:screen -L /dev/cu.usbserial-A402YSYU 115200 –L Note: Adding –L to the command, as shown above, turns on output logging so you can see the results of your commands. To end a session in Screen type Ctrl + A and then Ctrl + K to kill the session.
