acknowledgment is not received, the data will be re-sent (depending on the setting of the
AX25L2V2 command, it may send a poll first). The RETRY parameter will determine
how many times this is done before the connection is aborted due to bad conditions.
When acknowledgment is received, more data can then be sent. Therefore the
CONNECTED mode, barring impossible conditions, assures that data can pass from one
station to another correctly and in the proper order.
In the UNPROTO mode, data is transmitted with no acknowledgment expected or
required, and no retries are attempted. This mode is often used for transmitting beacons,
and for data broadcasts.
To manually type and send characters in UNPROTO mode, enter the Convers Mode by
entering the CONV (or K) command. Then, typed and entered characters will be
packetized and transmitted as data, and not be interpreted as commands.
When transmitting UNPROTO packets, the command called UNPROTO sets the
destination or “to” address of those packets. Its default setting is CQ.
To exit Convers mode and return to Command Mode, enter a <Ctrl+C>, by holding down
the Control key and pressing the "C" key.

A Simple Connect
To connect to another station, start from command prompt and enter a connect request.
For example:
CONNECT {callsign}<CR>
Where CONNECT is the command to establish a packet link with another station, and
{callsign} is the callsign of the other station. If the connect request fails, the following
messages will be displayed:
*** RETRY COUNT EXCEEDED
*** DISCONNECTED
When an acknowledgment is received for a connect request packet, the following
message will be displayed:
*** CONNECTED TO {callsign}
and the TALON will then change to the Convers Mode, or the communication mode
defined by the settings of the NOMODE and CONMODE commands.
Two commands determine when entered data will be packetized and transmitted. The
command SENDPAC defines the key or character that causes a packet to be transmitted.
