Hello,

I would like to verify that if I have chosen to use the picbasic method of RS232 interfacing with a 1K resistor from ( 16F877 ) portC.6 to the PC RS232 DB9 pin 2 and a 22K resistor from portC.7 to PC RS232 DB9 pin3, that I can not use the HSERIN or HSEROUT commands.

I tried and have no luck with the HW commands. Tried about every sample piece of code I could find in the forum.

SERIN, SEROUT commands on the other hand work just fine.

Curious why? I'm assuming it's to do with the data inversion as such...

Thanks,
Wayne
