Hi all, thanks for the help/advice!
Peter, the table you posted comes closest to what I was originally looking for. I think I
will end up just doing some testing to identify the troublesome control sequence and find
out how much padding is needed in each case. I?ll post back the numbers I find (thought
it may be a little bit before I get back to this particular project).
I do not think the VT100 supports hardware flow control.
Interesting the comments on the USB serial converters ? I am using a Keytronics (now
Tripp-Lite) USA-19H, and I think these are generally well regarded? But thinking on it, I
bet USB has something to do with it here ? perhaps buffer latency through the USB drivers
is keeping software flow-control (xon/xoff) from functioning effectively at higher baud
rates, which is another reason I think proper padding values might be a good alternative.
Another idea that might work would be to take an FPGA proto board that I have and hack up
a better serial port ? something with some buffering and xon/xoff logic sitting downstream
of the USB interface.
cheers,
