The Comtrol board worked fine, but as can be expected the system became loaded real quick under ISC with 4 high speed serial lines all locked at high baud rates, besides that the Hostess board has been loosing 1488s, 1489s and 8250s over the last 5 months, so I decided to send it back to Comtrol for repairs and 16550As. I don't know if the problem with the chips going was related to age or power supply problems, but one of the ports had no DTR, another no receive and a couple no transmit - and it finally got to the point where 3 ports worked out of 8. The board is 5 years old, and Hostess charges $10 for the 16550As, and $2 each for the 88 and 89s - plus a $50 labor charge which doesn't seem bad. A couple of months ago (this last summer) I played with the Digiboard top of the line 8 port 12.5 mhz board, as well as the Computone 10 mhz 80186 board with poor results. Last week I picked up another Intelliport board (actually 2 of them for $170 including shipping - but one of the I swapped for X windows) so here I am again with Computone products! My game plan is to limit the ports to one way communications (no bi-directional) with modems - 3 incoming and one outgoing and hopefully the Computone will work (fingers crossed). Right now I've been connected to my host on the first port, but I need some RJ35 to DB25 connectors before installing the other modems. I will keep you up to date. > Also, I'm no expert on the anvil board, but doesn't it have a switch > for interrupts?
