What is a Smartnet Arnet card?

Lots of jumpers on the back to swap pins about for DCE/DTE/combinations, but otherwise no electronics in there. The unit is a 4 port, and you add the expansion card to make it up to eight. The Smart port has intelligence on it, to take the load off the machine. They did a Multiport version which was just multiple plain old ports that you could address as serial ports at whatever IO addresses you configured the card at. The Smart port would need drivers installing. We used to use a lot of them in days when we ran multi-user operating systems on 8086/286/386 servers! There is a large box full of cards, and even more of the external boxes at the office. Manuals too. I've also got the Smartport SCO-Xenix drivers, and the diagnostic disc in front of me here (were in the same box as the wyse setup discs I posted earlier). If you want copies, etc., let me know! If you want an external box, I can do that too, for the cost of shipping. Regards Rob.
