Hi Jeff.
The latest image is 1.1.8a and is on the TAPR site. I have been using this
firmware running in the KISS mode on three different linux nodes with no
problems. In fact, one site has been running for almost a year at this point
without being touched. A couple of things to try...
1. Be sure your ftp client is in the binary mode. If not, it would
definitely corrupt the file data.
2. You mentioned this was an old TNC2. The original TNC2s only came with 16K
of RAM. Not sure at which firmware version support for 16K was dropped and
32K became the standard, but it was early. Binary images written for the 32K
RAMs will not work if 16K is installed. If you upgrade the memory, be sure
to read the TNC docs. If I remember correctly, a trace had to be cut and a
jumper installed. Ditto if the clock speed is changed.
3. If the LEDs cycle normally, but you are getting garbage on the serial
output (@9600), you may need to change the OpAmp on the RS-232 output. It
can appear that the TNC is not working properly if this is the case. The
replacement is a TL084 (I think). The problem here is the slew rate of the
earlier parts.
4. You could have bad RAM.
To put the TNC in the KISS mode, type KISS Y <cr>RESTART<cr> when the TNC
command prompt appears. You have to use the RESTART command, not RESET.
Thereafter, assuming the battery is good, the TNC will remember to go into
KISS when powered up.
Hope this helps.
73, John Bennett
