Drew -

Since there seems to be a fair amt of interest in this, I'm posting
to the net instead of sending directly to you.
I've been looking for full X.25 plp on a card for the AT but (actually
for a PC/RT, so things that rely on software running w/ DOS won't do).
Here's a brief list of some companies that offer some sort of hardware,
many of which I've rejected because of my somewhat restrictive needs
(e.g., they offer LAPB on the card but not PLP), but which may be useful
to you.

Frontier Technologies
P.O. Box 11238
Milwaukee, Wisconsin 53211
(414) 964-8689

        TCP/IP, X.25, HDLC on the card, w/ interfaces to all levels.

Eicon Technology Corp.
3452 Ashby St.
Montreal, Quebec H4R 2C1
(514) 333-8543

        Based on the Netbios interface. As far as I can tell has HDLC only
        on the board.

Scope, Inc.
1860 Michael Faraday Drive
Reston, Virginia 22090
(703) 471-5600

        Their DDN Microgateway has HDLC, LAPB, 1822 HDH, X.25 (presumably plp) and
        TCP/IP on the board. Also have a multibus version.

74 Northeastern Blvd. Unit 22
Nashua, NH 03062
(603) 883-0558

        HDLC/ LAPB on the board as I recall - better check w/ them on this.

ADAX Corp.
(415) 543-7047

        Primitive board X.25/HDLC, TCP/IP, SNA/SDLC in software w/ host overhead.

LYNBAR Datacom Products
Fort Worth, TX
(817) 431-3460

        Several products, HDLC, assumes DOS i think.

No info about these next few companies; I just received these addresses
from other sources but haven't checked them out yet:

INS Corp.
Mobile, Alabama
(205) 633-3270

ABM Computer Systems
3 Whatney
Irvine, CA 92714

S-Com Computer System Engineers, Ltd.
Tower House
High Street
Aylesbury, Bucks. HP20 1SQ

IBM also supposedly has a product announced in Paris but not in the US (?)
and I'm trying to find out about it but haven't learned anything yet.

I hope this is of some help.
