Hi,

can you help me, please? I did probe to send command to the USB modem Axesstel (connected via usbserial in my NTB) and then read answer. It doesn't work :-( Can you help me, please, where can be error? I did probe it under CentOS 5.4. Modem works OK, I am using it for connection. I was using this modem only like example for testing communication between NTB and other HW.


#!/bin/sh
stty -F /dev/ttyUSB0 min 0 time 0 -icanon speed 115200 cs8 -echo
eval POKUS=`cat /dev/ttyUSB0`
echo "ATZ" >/dev/ttyUSB0
echo $POKUS



Thank you

Rene

You may need to use an 'expect' script or if you can write perl - Device::Modem

cheers

What does it do wrong?

Using a shell to test functionality of a serial device is a recipe for frustration. Use minicom or C-Kermit, both of which are tools intended specifically for the purpose of serial communications.

Hi,

I did probe minicom (Linux), terminal (Windows). It works. I did probe modem only for test communication via Serial or USB port (curiosity) :-)

My test script answer me speed of my setting "115200" and not answer "OK".

Hi,

thank you for all infos and help. I did use other technology ... python and pyserial modul (http://pyserial.sourceforge.net/). It works ;-) When I use USB cable and set it via usbserial (ex. /dev/ttyUSB0), I can use it too. THNX.
