PK-88 OPERATING MANUAL
4.1
General Information
This section describes basic packet operation.
practice, the PK-88 is connected in a 'loopback' circuit so that it
'talks to itself.' You will have a chance become familiar with packet
operation before you actually go on the air.
We will describe commands used for routine packet operations. These
commands will get you ready for the section, 'Your First Packet Session'.
The 'Special Input Characters' section contains information on editing
from your keyboard and special characters used by the PK-88.
Most commands can be abbreviated by typing only the first two or three
characters. The mnemonics or minimum abbreviations for each command are shown
in Chapter 5, the 'Command Summary' chapter, along with a full description of
each command.
The PK-88 automatically enters the Command Mode when you first apply power. If
you have been in any other mode, type 'CONTROL-C' followed by a <RETURN> The
PK-88 answers with the following prompt:
cmd:
4.1.1
Change Radio Link Data Rate
The PK-88 provides radio link rates of 45, 50, 57, 75, 100, 110, 150, 200,
300, 600, 1200, 2400, 4800, 9600 and 19,200 BPS. The default data rate is set
at the factory for 1200 BPS.
Use the HBAUD command from Command Mode to read or change the packet link data
rate.
To read the present baud rate, type 'HBAUD <RETURN>' or 'HB <RETURN> The PK-88
responds with:
HBAUD
To chance the link rate, type 'HBAUD' followed two or three digits and a
<RETURN>
cmd:HBAUD 300<RETURN>
The PK-88 accepts the new baud rate and, if BBSMSGS is OFF, responds with the
old baud rate:
HBAUD
HBAUD
The number you enter becomes the new data rate and replaces the value
previously stored in RAM. You can also change the baud rate one step at a
time; For up type 'HB U' and for down type 'HB D'.
