PK-88 OPERATING MANUAL
3.3
Commands
The PK-88 Packet Radio Controller is a command-driven system. All control
functions are performed by typing single- and multiple-character commands from
your computer's keyboard. Menus are not used.
Commands can specify the variable values of the parameters that affect the
PK-88's operation and its performance during specific actions.
3.3.1
Entering Commands
Commands are entered after the Command Mode prompt: cmd:
NOTE:
Type <CTRL-C> if 'cmd:' is not displayed.
You will use English-like words or abbreviations to change the value of
parameters and issue instructions to the PK-88.
Commands are keywords or mnemonics (abbreviations that trigger your
memory) composed of strings of characters typed by the user.
You will probably never change the values of some parameters however, they
give each user the flexibility to adapt the PK-88 to the local environment and
operating conditions.
Use either UPPER CASE (capital letters) or lower case (small letters) when
entering commands.
End the command with a carriage return <CR> Carriage returns are not shown
in the examples below.
Correct your typing mistakes or cancel the line completely before you type
the final <CR> of your command.
See Chapter 3 for a discussion of line editing.
3.3.2
Command Responses
Whenever the PK-88 accepts a command that changes a value, the PK-88 responds
with the previously stored value (unless BBSMSGS is set ON, in which case the
previous value or state is not shown). For example, while in the Command mode,
if you type
cmd:xflow off
and 'XFLOW' was 'ON' you'll see the display
XFLOW
XFLOW
This message tells you that the value has been changed successfully.
