I found that for RS232 communications on COM2, JP5 needs to be 2-3 NOT 1-2. When JP5 was 1-2, I was not able to receive uncorrupted data. Similarly, I wonder if there is a similar problem with the CMOS jumper configuration. Can you guys verify for me that those jumper configurations for CMOS COM2 are corrent? My jumpers are current at JP4 2-3, JP5.2-JP6.2, and JP7 2-3 but I am NOT able to receive serial data!
