Hi,
I have been trying to output a data stream from an RS232 port to a
console window just to monitor raw data. However even simple text
output to a console using writeln seems to be terribly slow. Even a
simple
For i = 0 to 2000 do
writeln (i);
seems to be much slower than I would expect. The output rate increases
when the vertical scroll bar reaches the bottom of the console window,
and it seems to be affected by the screen buffer setting in the
console window, but even then seems to be very slow. Is this normal?
Is there any way to output text to screen at a significantly faster
rate?
Thanks
HMcG
