Title: Packet Radio transmissions.
Date: 20-Dec-83
From: Benny D. Miller Jr. WB8LGH
Protocal: At this time useing Dale Heatherington's
(of D.C. Hayes fame), packet programs,
modifyed for modem712, and m8modem
overlays.
To all interested in Radio packet transmisions. At this
time there are at least 2 packet radio stations in Columbus
Ohio, and more to be added within the next few weeks. We in
Columbus are going to re-write the current programs in 'C'
only with the AX.25 protocal, that seems to be in wide
spread acceptance. If any other stations, or persons are
interested in this form of communications, we can provide a
common place, and table for printing up info, to be
distributed. At this time their are about 8-12 in the
Columbus area that are interested, and proably will put
packet on their stations.
The current level of operation is simple to interface,
and can be made more complicated, as the pograms are
updated. At this time we have interfaced CP/M, and an MP/M
system. We hope that by shifting to th 'C' language (old
version in 8080 assembly) that this will open up other
processors, and operating systems to the packet system.
There are good argueing statements as to why not just
purchase a TNC (terminal node controller) and just use an
interface to communicate with the TNC. I'm not trying to
bypass the TNC, as they are very good designs, and good
support. Although there are many that feel their current
computers are not doing much, much of the time, and would
like to persue another avenue, and that is what we are
doing. While striveing to stay in, and within the stardard
communications.
So there it is in a nut (shell), and are, and will
continue to progress to an automated way to pass
documentation, public domain software and the packet
software (all will be public domain). In the Columbus area
we have passed several updated versions by radio just for
updateing, and will continue to do so. So I guess what I'm
trying to say is if you are interested, by all means call
the Columbus Ohio Remote MP/M system, and pickup any updated
software, or leave any modifyed software, or ideas for this
type of project.
