Subject: Linux node talking to BPQ node ??????/
Hi Om,
I have linked a Linux node and a BPQ node together over a serial cable using
KISS.
It looked that everything works fine but strange things happen....
When connecting from the linux to the bpq, every single command that I type,
the BPQ replies: Unknown command.
When connecting from the bpq to the linux, the linux node does not respond
at all. That is, the connection is made en than nothing happens anymore.
But sometimes....1 out of the 20....everything works well.
I think it has to be some kind of terminal setting but can't figure it out.
Any help?
Ronald

The term TNC stands for Terminal Node Controller. It is a unit that
contains a modem to convert the digital data into audio tones and back
again for interfacing to the radio, and a basic, dedicated internal
computer consisting of a CPU, memory and the programming for the unit on
a chip ("firmware"). It is capable of operating independantly of a
computer, and you only need to connect your computer to the TNC in order
to read the messages that have been sent to the unit, or upload
outgoing messages to it, or send it commands. Simple terminal software
such as Telix or ProComm is all that is necessary to communicate with
the device, however there is dedicated terminal software that is
available for this task that is more suitable and versatile.
You can eliminate the requirement for a TNC if you wish, however this
methood requires the PC to be in use and running the appropriate
software whenever access to the packet radio system is desired. BayCom
and Tigertronics have 300bps and 1200bps modems available in assembled
or kit form that connect to your serial port and your radio's speaker
and microphone jacks. You then run TNC-emulator software on your PC.
There are also higher speed modems available, such as BayCom, DXL and
YAM. These modems require connection to the internal circuits of the
radio in order to function, and not all radios are suitable.

There are also digital communications packages that use your PC's
sound card to emulate the function of the modem. Visit:

The speed of the packet radio link is determined by regulations and
the limitations of the radio's design. On HF ("shortwave"), Amateur
Radio connections at 1200bps and faster are not permitted in most
countries due to the amount of space they take up on the radio dial. The
faster data is sent, the more space it occupies on the radio bands. HF
data transmissions are limited in the amount of space they can occupy in
order to allow more users to operate at one time. On VHF and above, the
modem connections to the radio's speaker and microphone jacks will
distort the higher-speed data to the point where the data will not be
legible. 1200bps is used for easy connection to the radio's speaker and
microphone jacks. In order to operate at 9600bps and possibly 19200bps,
a connection to the radio's internal circuits is necessary, and even
then some radios will not perform properly. Speeds above 19200bps
pretty much require a radio specifically designed for high-speed data
transmission, voice-grade radios are not suitable.

In order to set up a packet radio station in a PRACTICAL sense, you
require a two-way radio for the communications link, an appropriate
modem (or TNC) to convert the data stream from your serial or parallel
port into audio tones (and back again) in order to enable the radio to
send and receive the data over the air, and a terminal program to run on
