Minicom mac serial#

Putty works well on Linux and offers some convenience, especially for serial communications.

The ins and outs of serial communications and terminal I/O are fairly complex you can read more than you ever wanted to know on the subject in the. Many terminal emulators also support file transfer protocols such as kermit or zmodem. This does quite a lot - it sets up the port, interprets ANSI or other terminal command sequences (ANSI was far from being the only standard supported by serial terminals). If you want to communicate interactively with another computer over the serial port then you will need terminal emulation software. Use to configure the port to the right parity, baud rate and other relevant settings. If you want to connect to a device and initiate automated two way conversations then you could see if will get you what you want. Put an entry in your file to run it on the appropriate serial port on a respawn basis. You can configure the system to allow logins from a terminal over a serial port by seting up a session on the serial port - getty is the tool for setting up a terminal and allowing logins onto it. Do you want to run a shell or applicaiton interactively from the terminal, connect out to another computer over the serial line, automate communication with a device over a serial port? If you want bidirectional communication then I presume you want something interactive with a human on the terminal. #!/bin/bash if $# -lt 1 then echo 'Usage:' echo ' femtocom. This enables you to use Ctrl+C or Ctrl+Z on the remote host, and to use interactive 'GUI' programs like aptitude or alsamixer. This script is based on, but sends everything over the serial port (except Ctrl+Q), not just single commands followed by Enter. I tried to do that, but the edit was rejected. Honestly, I wouldn't even mind if you just added my whole script to your post. To fix that you would need to use the trap command to execute kill $bgPid when the shell exits, like. If you kill it with Ctrl+C or with the kill command, then the cat process stays alive. Howerver, the real gotcha in your script is that the background process is only killed if you press Ctrl+D to end your script, because that ends the while loop cleanly. #!/bin/sh # connect.sh # Usage: # $ connect.sh # Example: connect.sh /dev/ttyS0 9600 # Set up device stty -F $1 $2 # Let cat read the device $1 in the background cat $1 & # Capture PID of background process so it is possible to terminate it when done bgPid=$! # Read commands from user, send them to device $1 while read cmd do echo '$cmd' done $1 # Terminate background read process kill $bgPid. I modified it to be more general and it fitted my purpose perfectly. I found a way using a shell script that put cat as a background process and a while loop that read the user input and echo it out to the port. It's probably some arcane configuration option, but whatever it is I can't figure it out (and this behavior has happened on more than one machine). For reasons I haven't figured out, minicom will sometime simply not send or receive data on a port that worked moments before or that picocom has no trouble with.

I've found picocom to be much easier to use than minicom. Picocom also will let you connect to a serial port without reconfiguring it ( -noinit) and will let you exit without restoring the serial port configuration ( -noreset or use Ctrl-A/ Ctrl-Q to quit picocom). You can query the communication settings using the stty program like this: stty. Notice that once you run a program like minicom, the port is left with the settings that minicom used. If it weren't set up appropriately, the cat and echo commands would not do for you what you might have expected.

Minicom mac install#

Installation Install the program with: sudo apt-get install minicom Alternatively, you can get Minicom via the Synaptic Package Manager.Д«ackground The main reason why you need any program like minicom to communicate over a serial port is that the port needs to be set up prior to initiating a connection. It is used to talk to external RS-232 devices such as mobile phones, routers, and serial console ports. Minicom Introduction Minicom is a text-based serial port communications program.
