Does Intel still make the HUB 6 port serial board? I am looking for an inexpensive UART based multiport board that is compatible with FAS, i.e. one interrupt for the entire board (non-sharable). Anyone have a used HUB to sell?

Intel is selling them until the end of '90, then they will be phased
out. Call any Intel field office or 1-800-INTEL-4-U.

Without special handling I doubt that FAS would handle the HUB6. It has an incompatible method for accessing the UARTS. Basically if memory serves .. you have two I/O addresses. You output the port number and the UART register number to the first port and then read/write to the second port. Suprisingly this does not add a very large amount of overhead to the driver if done right. If anyone is really interested I can dig out details. Assuming that FAS can be convinced to handle the I/O like that it would be able to handle the HUB6. And I have also put 16550's on a HUB6 without problems. -- Stuart Lynne Unifax Communications Inc. ...!van-bc!sl 604-937-7532(voice) sl@wimsey.bc.ca
