I have written a communication package that receives a 128 byte block
every 400 msec and has to respond within 40 msec. The comms package
worked okay using BC++ 3.1 & 4.5 & 5.01, but with DJGPP the CONIO
screen updates take too long and I can't responf within 40 mses. I am
displaying the raw data and the decoded data. I have looked at
PDCURSES and I can change over with a bit of work, but I don't want to
change if it doesn't help.

What package PDCURSES 2.2 or standard CONIO windowing has the faster
screen updates? 

Does CONIO have to switch to real (slow) mode to do the screen draw?
Does PDCURSES update the screen in protected mode?

Any help would be greatfully appreciated.

Regards,
Andrew
P.S. There's a beta version of PDCURSES available. It needs a small
amount of work to get it to compile (use 2.2 makefiles and modify as
required).
