RS-232 and INT_RDA

[Sirio]

I've got some problems with PIC16F876A and RS-232.
The communication work properly, but sometimes the u stop to receive data from rs-232.
I think is some overrun problem.

#fuses HS,NOBROWNOUT,NOWDT,NOPROTECT,NOLVP,NOPUT
#use delay(clock = 8000000)
#use rs232(baud = 9600, xmit = PIN_C6 , rcv = PIN_C7, ERRORS)
#use fast_io(a)
#use fast_io(b)
#use fast_io(c)

The question is:
how to manage and reset rs-232 errors?
Thanks.

There are two routes.
The first, is to monitor the 'errors' variable, that you have allready specified to use. The second is to go 'DIY'. Have a look at my post about handling an 11byte packet, where I clear the overrun error.

Best Wishes
