Query modem with ati7 and sen result to log file.

[JohnLynn]

I need to script some way to query a modem and send the result to a log file.

I have tried cat and cu. I can not seem to get the debug into a log. Dont care which tool I use.

Thanks for the review.

Write a shell script to query the modem and send the results of that shell script into a log file. Then parse as needed. You can do this one of two ways:

(Inside the shell script)
exec 1>> modem_query.log # Some log name, STDOUT
exec 2>> modem_query.log # Some log name, STDERR

OR:

./modem_query.ksh > modem_query.log 2>&1

If you do not want the errors, then send them to /dev/null.

SOLUTION, read man page 499 times, tested with
cu -d -l /dev/ttyS0. Lots of help from Google and a little luck and lots of tries.



#!/bin/bash
# this script is to return the modem type
# you could use it to dial just as easy
# atdt1234\r instead of ati7\r

{

# one char at at time
echo -en "a"
echo -en "t"
echo -en "i"
echo -en "7"
echo -en "\r"
sleep 1
echo "~." # exit

} | cu -l /dev/ttyS0 >> log.txt 2>&1
exit

thanks for the help
