First let me say that I'm still in the prospective phase, deciding what to 
buy. I have no system running.

Two ideas came to mind: using some combination of MacX25+Apple NB Serial 
Card, or the Symicron X.25 board for A/UX (appears in the A/UX application 
list on Applelink; I haven't their coordinates here, but I can look it up).

As far as I know (following the recommendation of a knowledgeable Apple 
guy and considering the information I got from Cisco), the Cisco solution 
should work for your problem. Another (cheaper) possibility might be to 
use a couple of PAD boxes and Hayes Interbridges, or a similar AppleTalk 
bridge for modem connections:

LocalTalk1--Bridge==X.25 PAD box< - - >X.25 PADbox==Bridge--LocalTalk2

"---" is LocalTalk, "==" is RS-232, "<- ->"  is the X.25 net.

But I'm ignorant in these matters... Does this make sense ?

Finally, although I'm also very interested in connecting AppleTalks over 
X.25, my current problem is making TTY-like access to a Mac A/UX host. 
Implementing an AppleTalk bridge would be an overkill for my application.

Best wishes,    Miguel
