See the “Command Reference” for the possible values for each parameter
(e.g., see the HBAUD command for possible hbaud values).
Command Mode
In order to change parameters, or give any other instructions to the TNC, you
must be in Command Mode. This is the mode you will be in when you first turn
on the TNC or after resetting it.
Once you have left Command Mode for any reason, there is a parameter called
COMMAND that determines what special character you will use to return to
Command Mode. This comes defaulted as a <Ctrl+C> (i.e., while holding down
the control key, press “C”, then release both keys).
Whenever you enter Command Mode the TNC will send a prompt to your screen
that looks like this:
cmd:
Connected vs Unproto
There are two ways to send data in packet radio, connected or unproto (uncon-
nected). In the Connected Mode you first establish a connection. Then your TNC
will send packets to that specific station and expects acknowledgments in return.
If an acknowledgment is not received, the TNC will resend the data (depending
on the setting of AX25L2V2, it may send a poll first). The RETRY parameter
will determine how many times this is done before the connection is lost due to
bad conditions. If the acknowledgment is received, the TNC is happy and will
send more data when available. Therefore the Connected Mode, barring impossi-
ble conditions, assures that the station you are connected to will receive every-
thing you say, and in the order you say it.
