That reminds me of a question I have been wanting to ask for a long time.
Can one configure the vanilla V/AT 2.3 (or later) driver to use four serial
ports which correspond to COM1-COM4 under DOS 3.3 (and earlier extensions)?
Usually they are set up as follows:
Board 1: First port is COM1, IRQ 4, Address 0x3f8
Second port is COM2, IRQ 3, Address 0x2f8
Board 2: First port is COM3, IRQ 4, Address 0x3e8
Second port is COM4, IRQ 3, Address 0x2e8
This would be using standard AT I/O cards using either of the two standard
uarts.
If not (and anyway :-) --
Stuart Lynne, are you listening? When is your driver going to be ready?
Will it support this type of configuration?
