Here's what's odd, I kept hearing that, yet I'm up to about 7-8 different radios of different generations and CPS's that work find fine with FTDI USB to Serial devices and dosbox:
I think most of the "windows emulators don't work" myths are
really just issues with the chip in the USB to serial adapter.
I have some non-FTDI based cables that work fine with windows
native CPS's, but not with the old DOS based cps's. So there is a
reason the ebay cable sellers list if their cable is FTDI based...
it makes a difference.
So while I have old notebooks still with "real" serial ports, I
have never had to use them. Yep, sometimes I have to try a few
different speed settings on dosbox, but usually something between
500-800 mhz 386 equiv works. And it's just Ctl-F11 and Ctl-F12 to
make faster or slower. So very quick to get them to read, usually
only takes 20-30 seconds to home in on what works. And I keep all
my cps and files on my modern computer.
The radio does not know what's attached to the serial port. There
are only three issues which can make a difference, and two of them
are due to CPS coding:
- Voltage on various HW pins. Most modern (FTDI and newer) based
chips are fine in this regard. I think this is the main thing that
bites folks, using unknown USB to serial chips
