Re: Kannel and GSM Modem

We use ser2net (http://ser2net.sourceforge.net/) to accomplish this. 
Have kannel running in a virtual machine, connecting to GSM modems on a 
physical Linux machine over IP.

In Kannel conf instead of:

device = /dev/ttyS1

specify:

device = rawtcp
host = ser2nethost
port = ser2net-modem-port

Note: ser2net doesn't provide any authentication mechanism, so you'll 
need to limit access to the port(s) in some other way.

If you talk about access from kannel to the gsm modems, there are some devices which have a gsm modem built in and then present it on a ethernet (usually for IP dial-out). Kannel doesnt need TCP/IP to talk to the modem but a serial port. I have some boxes out of china which connect 16 or 32 or 64 GSM modem to a computer by a simple USB cable. The computer will get the same amount of serial ports which then can be used directly from kannel.
