Dear All,
I am using ARM9 based ATMEL AT91RM9200 microcontoller for a communication project. I
am using a custom designed PCB. Problem is when i am receiving data via serial port, some
times the controller got hang up. Need to restart every time. I am using RS485
communication and receive data via ttyS3 port. Presently i am receiving data
in non-cannonical mode. controller have the time out value of
120microseconds for every byte.Someone can tell me how to handle timer and signal handlers.
Thanks in Advance,
Regards,
Baaski
