Hi - I am trying to configure some network switches which require an RS232 connection. I thought I had just the machine when I fired up my PC/XT. Turns out the thing has a parallel port on a mono card (yes, a mono graphics card which also has a parallel port on it, weird I know - the card is called a PERSYST MONO II). Anyway, I would be very grateful if anyone out there could arrange a suitable price of either a multi i/o card (parallel & serial to replace this mono card which I thought was a multi i/o), or failing that, just a standard 8250 or 16550 UART based serial controller with RS232 (either DB9 or DB25 is fine).
The card will need to be compatible with an IBM PC/XT, so it needs to be an 8-bit card, not an EISA/16 bit card.
I looked on Trademe first but right now there's nothing out there.
Thanks very much,
Ali.
