THANKS, STeve!!
The characters were actually going the right place -- where the code had sent them.
I found my old code for driving a HEATHKIT SB102 from Winlink....and it interprets FT-897 commands.....oops!
I almost got THAT kludged in...but I have to go back because I am not handling the received characters properly.? ?The previous code was written for a completely different purpose, so a good bit of re-thinking and rewriting is now in order....however, I am ON THE WAY!
I put another hour into it to see characters getting stored and attempted to be interpreted.? ? That was big improvement, but all needs careful rewriting.
Another few hours and I might be intepreting my first command properly.
I have the baud rate set at 115200 on the theory that I dare not SLOW UP the SDR functions inordinately.
Timing will be something I have to figure out eventually.
But at least I am now processing characters from WINLINK itself, even if poorly.? ?It serves as a proxy for all other WINDOWS software that will likely work quite similiarly.??
I should order a couple of UARTs or at least some Baofeng programming cables, whichever is cheaper.? ?
Found this:? ??
It is TWO uarts identical, with connection pins (which will need to be longer, but I think I have some or can make them.? ? $9
That should fill the bill and make my llfe easier.
UPCOMING TALK:
I am giving a? 50-minute TALK about all the improvements that have been made to the sBitx in the past year, at the West Central Florida TECHCON 2024 talk at the end of February.? ?It would really be nice if I had this WORKING by then....it would mean that almost anything could be done with the radio, some all by itself, and others, such as WINLINK RMS 24/7/365 gateway stations, or ION2G, by using this trick.? ??
