Hi Barry,
Thanks for sharing this driver. Do most modern builds of NitrOS9 have
everything I need to compile this using the 'asm' command?
Can an RS232 driver be replaced on "live" system and does a new boot disk
need to be created?
I'm looking at some of the driver source below and it's not entirely clear
to me what the comm port settings are.
Thank you for your help!
