A relatively lightweight PC at his business, with
internet access and a
serial port, running linux and kermit, should get him access. For
certain values of soldering in the missing serial port, even one of the
linux-based linksys routers could probably be made to work.
SSH from the mountain to the PC/linksys, kermit to
PDP.
I use a hardware TELNET <> LAT gateway, so I don't have to deal with
power hungry multiplexors, serial cables, and baud rate limitations.
Of course, since he's probably running V5A, he couldn't get that fancy.
However, a plain ol' terminal server would be much easier to implement.
Set the router to direct TELNET traffic to the terminal server, and voila !
