Greetings,
Is it possible to run uucp through a MILNET TAC? We are about to place
a PC-AT running XENIX in Washington DC and wan't it to be able to
routinely transfer mail and files to and from our VAX (4.2BSD) here in
San Diego. We are a MILNET host. I hate the thought of long distance
phone calls 3-4 times a day. If anyone has done it would you please
send me the appropriate incantation from your L.sys file (with the
names/numbers changed to protect the innocent of course).

Running KERMIT and UUCP through the TACS is a miserable idea that DCA wishes nobody had thought of. UUCP's link protocol is strange enough that I don't even know if it's possible to make it work. TACs are not and can not be made to work in transparent mode. In addition, they operate with a TCP window of 64 bytes which would, combined with the general low bandwidth of the MILNET these days, make your effective rate very, very, slow. As Col. Maybaum once said, "These guys are ruining my network a character at a time." -Ron

It looks like setting up a link with a uucp site in the DC area is the
best solution (Rick@seismo has already generously offered his site).
Thank you all for you responses.
Ironically enough I'm putting the system in DC to eliminate some of
that "charater at a time" traffic. The people there now currently
use a TAC to access the VAX(s) here. But, the eliminated "character"
traffic is now replace by the need for "bulk data" traffic. Which
it appears can't be done directly.
Is anybody working on a general solution to this problem? I hope so,
since it's going to get worse. For the Navy, OPNAVINST 2070.4 requires
use of the DDN as the primary data communications medium. It seems
silly to permanantly attach a PC to an IMP just for mail and an
occaisonal file transfer.
Maybe something like a dialin UDP port.

You can run TCP/IP over dial up lines, Dave Mills is perhaps the pioneer in hooking up micros in this fashion. However, there is no TCP/IP for the PC yet outside of the MIT code which is pretty bad. Perhaps Excelan or CMC will make one of their little protocol cards that will fit into a PC slot someday. -Ron

Excelan has made one of their protocol boards to fit in the PC slot, it is on their latest price list. BTW, has anyone used one of these CMC or Excelan boards with its optional serial port?
