Hi
I'm trying to write a driver for modem, to work like windows terminal sending and receiving AT commands. Has anyone tired to do this ?
I'm receiving sometimes right string sometime wrong string, I changed the baud rate but not succesfull.
right string

RING
+CLIP: "phone nr.",129,,,,0
and wrong string :
,,,,0

+CLIP: "phone nr",129,,,,0
If any one have the driver I would be very happy.
