Rich,

I am quite sure that your problem is the EPROM.  TheNet is a special
networking EPROM that will never work with UI-View.  I think that TNC is a
TNC2 clone and if that is the case you need to get the latest software
loaded into the EPROM.  If you do not have access to a prom programmer I
can help.

Should the DataBits be 8 and not 7

Hello,
Is there a list of telemetry types that are supported by the APRS protocol
somewhere?
Thanks!

I had a look in my "Dinosaur" box from my old packet days and found a new 
PacComm DR100 Digipeater (circa 1987) in box, unused. Even has the 
programming donge thing with it.

Yes.    7-E-1 is an obsolete hangover from the mid 1970s when packet was
born.  At that time, before personal computers, the dumb terminals and
Teletype machines widely used with minicomputers (and also with and early
TNCs) almost universally used 7 bits even parity.   This was before
personal computing and binary files with 8-bit bytes.  [Mass storage was
something you did with punched paper tape with 7 holes across the width of
the tape.]  Somehow this configuration persists to this day as the default
setting in TNCs.    For operation on APRS, you want 8-bit transparency.
For most TNC2 devices and similar, the TNC init file needs to issue the
commands

8BIT OFF   (meaning don't mask incoming 8-bit bytes off to 7 bits)

AWLEN  8   (meaning use 8-bit long full bytes)

I have modified the final release of the official TAPR firmware (Ver 1.1.9)
to power up in 8-N-1 instead of the original 7-E-1 mode which makes it much
more convenient for modern computer applications.    A binary file of this
modified firmware, which can be used to program an EPROM, is on my website
at:


On this download page of miscellaneous files and reference sheets, look for
the file

TNC2-119b-8N1Mod.zip

As a added bonus, this release of the TNC2 firmware includes KISS mode, and
alsd the first (and last) explicit support for APRS in the form of a dumb
APRS tracker mode.  From an attached terminal, you command the TNC into the
tracker mode, disconnect the terminal and then connect a NMEA-format GPS to
the serial port.  The TNC will then transmit raw NMEA strings over the air
in a manner similar to the dumb tracker mode on a KPC3.

Just above this item in my MISCINFO list  is a quick hack I threw together
years ago in compiled Quickbasic (i.e. standalone .EXE) to send the command
sequence to get a TNC out of KISS mode.  Look for

KISS_OFF.EXE

Google for APRS Telemetry.TXT nd you will get this page:

http://web.ew.usna.edu/~bruninga/ande/KPC3-telemetry.txt
About the KPC-3+ TNC telemetry which is in APRS format.

For full information, see the original TELEMTRY.TXT

http://eng.usna.navy.mil/~bruninga/APRS-docs/TELEMTRY.TXT

Notice the intentional misspelling to make it fit an original 8 character
file name.

Actually, it makes the TNC function as a NODE, not a digipeater.  This
terminology is the source of confusion in several areas, what with people
putting up nodes instead of digis, calling a dig a node, etc.  We need
digipeaters in APRS, not nodes.  But Stephen is right -- it won't work with
APRS software at all.
