The last 2 weeks I am busy to get all the networked multi/multi PC's ready
for the upcoming PACC contest at PI4COM.
I am working now on a PC which give my problems in CW.
We use the LPT1 port for CW (just a normal CT cable).
I think there is a timing problem in the computer.
When transmitting some letters or figures, they are totally disturbed (no CW
at all hi).

I am working with W98 second edition (including the latest patches).
The hardware is a Tulip Vision Line P5/166 64 Mb memory.
There is an internal network card available.

I disabled all the hardware that I don't use (like USB and second COM-port).
I changed the LPT1 port from output only ==> ECP ==> Bi-directional.
In the writelog.ini I put the line: LPT1:0x378 (the same port as in the
The virusscanner is disabled.

So there is nearly no difference at all changing the parameters.
All the other PC's worked fine (even they are slower than this one).

I hope that someone has a good suggestion for me.
