I think there may be a solution with this performance counter for my purposes…
here’s what I’m trying to accomplish:
I’m trying to read a string from a serial port until I get a linefeed, but I
don’t want it to get stuck in an endless loop which could happen if:
A: nothing is ever received

I don’t need a 55mS tick, there was a DOS timer that ticked every 55mS, which I
used to calibrate a delayloop.. however I can’t use any of that on windows, I
can’t even make the DOS function call, and even if I had a way to calibrate my
delay loop, it would be meaningless because I have to share

Any Suggestions for a microsecond delay? I had a scheme in my old dos program
where I would run a massive loop at the beginning of my program and time it
with DOS 55mS ticks, then do the math and figure out how many times I needed to
loop for a given delay.. worked great on DOS with nothing els

Why do you need this 55mS tick?
