Hi Al,
For some reason my mind locks up in respect to this thread... It must be the subject line :)

Thanks for the tips.

Truth is that we are redesigning the app in VFP using MSCOMM32 instead of Silverfox, and different hardware for serial ports board, and the old computer will soon be replaced, so there is very little enthusiasm from hardware guy to fix the old stuff (excepts when the app stops working!).

Thanks,
dz
