Hello everybody
I have a device (GSM modem) connected to the serial port ser2. I deactivated
the debug in the kernel and so on.
Now the device works very well. 
But if I disconnect and reconnect the device i.e. the GSM modem, so I can
send strings to the Device, but I cannot
 receive anything. That's my problem. The device answers, but I didn't get
I tried to close and open the serial port again, but it doesn't work. 
If I test my program with ser0 (the first serial port) it works. I can
disconnect and reconnect the modem and I 
get the strings. What's the problem with ser2?????
Can anybody help me, please??
