- Hate to tell you, but the *only* mud code you're going to find is for
- TCP/IP. Though there is one that works over Appletalk on the Mac, I
- guess (hadn't thought about that). You're either going to switch over
- to TCP/IP (easy) or totally rewrite the MUD driver (not so easy).

- There's nothing weird about that at all. In the early 60's the US military
- ran a 4 channel multiplexed RTTY link between Washington and Honolulu via
- EME for several years although for a 2 Mbaud data rate I think you'd need
- a bit better link margin than you mentioned. I'm surprised that it hasn't
- been done already. With the current decline in the solar cycle one system
- like this would probably be able to handle 80% or more of the transatlantic
- packet traffic.
- Any volunteers?

- I don't recall RSX being particularly derived or inspired from CPM...and i
- recall there was some way to handle directories and such on RSTS/E (around
- 1975 or so...it's been a while...).
-
- the whole computing world didn't start with unix or CP/M.
-
- and heck, PIP a problem, nayhh. in a way it was pretty neat...

-
- I can't speak for the MFH-12745C, but I have been using an MFJ-1278-T
- (multi-mode TNC)for about 2 years, and it's worked flawlessly.
-
- It came with a terrific 1.5" thick instruction manual detailing every aspect of
- operation, including installation instructions for several popular radios, as
- well as a complete guide to user alignment of the filters and modem.
-
- I've dragged my MFJ TNC into the woods camping dozens of times now,
- operating it and my VHF rig on batteries without a single failure or
- complaint. I love it.

- How do I define the TNC interface to SCO UNIX or Linux? A local user plans to
- run native unix or linux via TNC and needs to know how to set it up without
- running NOS under unix.

-
- Hi folks,
-
- Apparently there are problems with X1JR2 which result in "node busy"
- messages and require a reset.
-
- 1. Do I understand correctly that there are no further revisions planned?
-
- 2. If that is the case, does anyone know if the source code is available
- and, if so, where?
-
- 3. Is anyone else working on the problem?
-
- Thanks, & 73,
-
