DOS serial port setup for RSS?

[Rred]

I'm trying to set up an old computer from scratch to make some obsolete programming softwares happy. To do this, I've set up a DOS (FreeDOS installed without complaint after MS 7.10 wouldn't) boot drive and a multi-boot option by installing XP after that. And the machine has a real serial port. But.

When I tried the RSS software, which had worked last year when I booted DOS from a USB (using UEFI) drive, and hooked up the exact same ribless cable I used last year, same radio (HT1000) all I got was the message that there was an error communicating with the radio. Apparently either the cable has gone bad or there's something in the serial port setup that isn't right.

So question #1: Does the RSS software expect to see any special serial port configuration? Maybe using the old DOS MODE command to set the baud rate, parity, data bits, stop bit like "mode COM1:1200,n,8,1" or something similar? Is there a top baud rate that RSS needs to see?

Similarly, is there any need (or way) to set XON/XOFF, CTS/DSR, DTR/RTS? I don't ever recall using MODE to force those, but I'm looking at what might be wrong before I try something like another ribless cable.

Its that familiar feeling that there is something simple and wrong and I'm just missing it.

I have never had to adjust any serial port configuration however if my memory serves me right the baud rate should be 1200. However, I always thought that CPS set this for some reason. I could be wrong on that however.

Correct,RSS sets up the Serial port.
