Re: Serial Link



Here's mine:
Windows 3.11
4 COM ports
COM1 IRQ4: Serial mouse
COM2 IRQ3: External modem
COM3 IRQ9: Sharp Wizard Linkcable
COM4 IRQ9: TI Graph-Link.
I can use either my Wizardlink or the Graphlink while I'm online, but not
both at the same time.  The key is the IRQs.  you can't have two devices
open at the same time if they use the same IRQ.
