Packet-Radio Operation
This section describes basic Packet operation. You'll learn quite a bit about your PK-232's
Packet features and control operation without really sending anything over the air. For your
first Packet practice, the PK-232 will be connected in a "loopback" circuit so that it will "talk
to itself". You'll have a chance become familiar with Packet operation before you actually go
on the air.
We'll describe the commands you'll use for everyday Packet operations. These commands
will get you ready for the section "Your First Packet QSO". The "Special Input Characters"
section contains information on editing from your keyboard and discusses other special char-
acters used by the PK-232.
If you intend to use your Packet station for advanced" applications, such as a Bulletin Board
System or binary file transfers, read the chapter on "Advanced Packet Operation".
Most commands can be abbreviated by typing only the first two or three characters. The
"mnemonics" or minimum abbreviations for each command as shown in the "Command
Summary" chapter, along with a full description of each command.
Your PK-232 automatically enters the Packet Mode when you first turn on the power or type
RESET
the
command. If you've been in any other mode, Type
<RETURN>. The PK-232 answers with:

Change Radio Link Data Rate
Your PK-232 provides link rates of 45,50, 57, 75, 100, 110, 150, 200, 300, 600, 1200,
2400, 4800 and 9600 BPS. The default data rate is 1200 BPS when you start your PK-232
for the first time.

Use the
To read the present baud rate, type
sponds with:
HBAUD
To change the link rate, type
HBAUD 300<RETURN>
The PK-232 accepts the new baud rate and responds with the old baud rate:
HBAUD
The number you enter becomes the new data rate and replaces the value previously
stored in the program. You can also change the baud rate one step up or down one step
at a time by typing
and adopts the new rate.
