Hi,

This is fine

Code:

#use rs232(baud=57600, xmit=PIN_C6, rcv=PIN_C7, parity=N, bits=8, stream=GPS, ERRORS)

This not working

Code:

#use rs232(baud=57600, UART1, parity=N, bits=8, stream=GPS, ERRORS)

Why?

Thanx in advance for help!

'UART1' isn't supported in version 3.249.

Look at the new features for vs. 4, on page 14 of this document:
http://www.ccsinfo.com/pdfs/v3.to.v4.pdf
It says:

Quote:

#USE RS232() upgrade

The powerful RS-232 library upgrade in Version 4 includes the following options:
• Two additional parameters to #use rs232(): UART1 and UART2.
