Two questions re serial ports and communication software under Xenix on the PC-AT : 1. Is there a multiport board serial RS-232 type board available now with software drivers to support /dev/ttynn's other than the board made by digigraphics? 2. Is there a smart-terminal type comm program that will allow users to access databases on-line via modem and up/download files (a la PC-TALK et al). Thanks for any recommendations.

The PC only has 2 interrupts available to com (1&2). Therefore this type of card has to either: Have the ports polled for characters or Have the ports share an interrupt vector with the driver checking to see who is calling. Regretfully, I don't have any more info on hand. Any PC rag readers out there with more info? -- Opinions expressed are public domain, and do not belong to Lotus Development Corp. ---------------------------------------------------------------- Simcha-Yitzchak Lerner {genrad|ihnp4|ima}!wjh12!talcott!sesame!slerner {cbosgd|harvard}!talcott!sesame!slerner talcott!sesame!slerner@harvard.ARPA

I have been using the ATvantage-X card from Computone. It is an 8-port serial board that contains its own processor, to off-load the '286. I believe AST has a 4 port board (you can use a total of two) that are of the non-intelligent variety. Computone's board is around $1k. Call Jack Berlin, product mgr, at 800-241-3946. For comm software on Xenix, I have been using Pro-Yam, from Omen Technology, 503-621-3406. You buy the PC-Dos version, then can download the Xenix version from their bbs. The author, Chuck Forsberg, can also be reached at ...!tektronix!reed!omen!caf. I also have info on a product called MLINK, from Corp. Microsystems, 603-448-5193; I'm not sure if they have ported to the AT yet.
