On an Acer travelmate I use the serial gate to feed HF Fax signals
from a controller interface to SSB receiver.

Happens that the received image makes small jumps to the left at
regular intervals. Resulting an image with large left shifted stripes.

This seems due to some PC activity interrupting the incoming data
stream for very short spot, but enough to cause that jump.

First idea was to disable battery status checker and Power management
system, but I got no result.

Do you have any other idea ? to make test on it ?
Thanks

Gotta find whats accessing the drive, or CPU. Make sure no virus
protection running. You might want to totally shut down all unused
programs before you run fax. Ctrl-alt-delete will let you do that, or
you can get programs to shut everything down. "IE: game launchpad,
etc"..I've seen quite a few people have this trouble when running
SSTV. Usually, you will notice a HD access when that happens. Watch
the red light...BTW, make sure no BIOS anti virus is running either.
You might be able to use Dr.Watson to find the running process, if you
can't nail it down. MK
