I am using the USB to RS232 units from serialio.com, Belkin and Cablestogo.com These are working fine, even with my ancient dos version which I run in a dos box under windows.
Have you tried those adapters?
PS. Yes I can set them to COM1 if need be.
Does anybody know if there is a laptop out there that has a 17" screen, either 1050x1600 or 1920x1200 resolution, that also has a serial port onboard??
I program specialized control systems that need a lot of screen real-estate, but that communicate through serial, and I'm looking for a replacement for my old beast.
There's some Dell that have 15.4" screens - but I'd really like 17" with the numberpad.
