Ok, here's the deal. I'm trying to write a program to decode
some of the various digital radio signals used by hams, on shortwave etc.
The data is coming out of the radio as audio(FSK). I can demodulate it with a
PLL
and convert it to RS-232 levels and deliver it to a pin on the serial port. But
I'm having a hard time figuring out how to look at it in VB5.
I need to identify the baud rate-which is not always a standard one.
Word lengths vary and I'd also like to be able to identify the mark/space
frequencies.Keep dreaming huh?
Well there are DOS programs out there(a couple of which I've written)
that can do it.This windows stuff isn't as easy.
Anyone out there have any suggestions on how I can do some of this ?
All I Need Is A Push In The Right Direction.
Thanks,
Jim

Is your problem accessing the serial port?  I may can help if this is the
problem.  VB is difficult in that respect but there are ways to get to the
I/O if needed.  If you have VB professional or better look for a control
named MSCOM which allows one to do some communications with com ports.  DLL
programming might provide better results.  There are simple ways to access
several control bits on the RS-232 line at the DLL level.
