For this reason a multiplexer protocol is supported in GSM 07.10 which creates several virtual serial ports which can be controlled with normal AT commands. The AT commands are routed through a software multiplexer circuit which on the other end is connected to the real GSM modem's tty. Is there any GSM multiplexer protocol for linux available? Unfortunately, I did not find any driver in the kernel or userland to support this. I did find out so far that RFCOMM might be a good point to start writing virtual tty ports as bluetooth also supports GSM 07.10 in connection with the RFCOMM protocol. The basic idea behind it is to interface the sock to a the GSM modem TTY instead of L2CAP. Any hints? Thanks regards Dani -- swissEmbedded GmbH Daniel Haensse, Dipl. El. Ing.
