I've read another forum post or two about a similar issue, but none seem to solve mine. I'm trying to get some old software working that is DOS-only on my Windows 7 PC. I've got the program booting and running fine, but I can't get it to talk to my radio hooked up through the serial port for programming. I have the config file like so:
serial1=directserial realport:COM1 rxdelay:600

I've tried various rxdelay values from 20 up to 600 with no luck. I'm using COM1 which I have verified is correct within windows, since it is the built in COM port on the desktop. I'm getting this error in the status window:

Serial1: Errors: Framing 1, Parity 0, Overrun RX:0 (IF0:0), TX:0, Break 1
Serial1: Errors: Framing 0, Parity 0, Overrun RX:15 (IF0:0), TX:0, Break 0

The moment I turn my radio on, those errors occur. If I turn it off then back on, they occur again consistently. Any ideas?

Thanks!
