Minicom runscript does not understand variables

Question

I've been trying to execute a simple runsript that reads in a variable $1 and passes it out as serial data using the "send" command. I've had no issues sending text with that command in a script, but I dont want to write multiple scripts just to send different things. I'm not sure if I'm approaching this right. here's the code I thought it should be: (file is commands.sh)

#!bin/bash
send "$1\c"

when I run minicom -S commands.sh "flick servo" i get:

minicom: cannot open /dev/modem: No such file or directory

any ideas? I'm open to alternate ways to send text via terminal

Answer 1

The script is a minicom runscript, not a shell script. Naming the script .sh or adding a comment saying !bin/bash does not change this. -S also doesn't accept arguments.

If (and only if) you can successfully run minicom -S hardcodedscript, you can use environment variables to parameterize it:

Make a commands.rs:

send "$(THING)\c" 

then

THING='flick servo' minicom -S commands.rs
