OK normally follows the SIGNAL command after it has determined the class and
speed of the received station. Typing OK will change the commands RXREV, RBAUD
or ABAUD and OPMODE to their proper value. If the SIGNAL command did not reveal
any useful information, typing OK produces the "?bad" error message. Typing OK
when not in the SIGNAL mode produces the "?not while in (mode)" error message.

Opmode Immediate Command
Mode: Command Host: OP

OPMODE is an immediate command that shows the PK-900's current mode of
operation on Radio Port 1 as well as system status. Opmode also displays the
MORSE speed when in the Morse mode. Use the OPMODE command at any time when
your PK-900 is in the Command Mode to display the present operating mode.
Here is a typical example:
