>No matter if you're using a W9x or NT, you may be in trouble using a modem from a DOS task,

I am using COMET to access the serial port, no modem.

>Another thing - I've tried to run FPD on a NT WS machine, and though it worked fine from the default setting, I needed to set up a DOS codepage 852 and local keyboard layout, so I had to make local autoexec.nt and config.nt. I remember having to do lots of tweaking of memory settings - Watcom extender complained a lot. I've tamed it, finally, but the rest of the machine went to hell - the disk had to be reformatted, and I don't remember what was the winning combination in these .nt files.

I will keep this in mind.

P.S. I have the DOS app a try and it worked like a charm. I will be doing a longer test (24 hours) later this week. Thanks for your input.
