Hello
I am using linux 2.6.24 and I am trying to make a TELIT 910 running by using the option.c and option.ko module
It seems that data are sent from Linux to the modem and in my buffer I never receive any data ( but I am able to control led on the modem by using AT command through the write() function. (using ttyUSB4 or ttyUSB5)
If I enable the GPS this one broadcast data on other port and I am able to read data on my buffer ( ttyUSB3)

I tried to debug my option driver but it looks it doesn"t call function like : option_open, oiption_write.

Thnaks for your support I think I am closed to final solution
REgards,
