#106993 - still same problem... Responding to: ???'s previous message |

If you urgently need the parity check, then you could transmit 7bit ASCII in an 8bit frame, filling the 8th bit with your paritiy bit.
Kai Hi, I rewrote the program as you said....7 bit ASCII in a 8 bit frame and checked for the parity....for example.I put 0110 0010B in Accumulator and checked for parity, if parity flag is set, then I would ORL A,#1000 0000B and then transmit the byte.I configured the serial communication software as 9600,Even,8,1 and the received byte was 1110 0010B.But when I changed the configuration on serial communication software to 9600,Odd,8,1 the byte received was 1110 0010B!!! The problem seems to be persistant... The configuration of serialwatcher.exe was PORT NUMBER:Port 1 DATA WIDTH: 8 bits PARITY: odd HARD. HANDSHAKE:None SOFT HANDSHAKE:None ENABLE: DTR RTS SPEED:9600 |
