This program will read a file (or stdin) containing a list of AT
commands. Each command will be send to the modem, and all the response
for the command will be output to file (or stdout).
Example, to hang up any ongoing call:
$ echo ATH | atinout - /dev/ttyACM0 -
ATH
OK
$
Features
- Sends AT commands from the command line
- Allows for capture of the responses from the modem
