PK232.25
THIS BUG APPARENTLY DOES NOT PRESENT A PROBLEM TO THE VAST MAJORITY
OF PK-232 USERS. IT NEED NOT CONCERN YOU IF:
.
YOU HAVE NOT CONNECTED THE SQUELCH SIGNAL LINE BETWEEN
YOUR TRANSCEIVER AND THE PK-232 (PIN 3 OF THE RADIO 1
AND RADIO 2 INTERFACE CONNECTORS), OR
IF YOU HAVE MADE THE CONNECTION, LUCKY ENOUGH TO OWN A
TRANSCEIVER THAT PROVIDES THE CORRECT SIGNAL SENSE TO
THE PK-232 FOR THE PROPER OPERATION OF RF-CARRIER CSMA
WITH THE PROGRAM DEFAULT VALUE OF NEG FOR THE SQUELCH
PARAMETER.
.
THE BUG IS EXHIBITED WHEN THE PROGRAM INCORRECTLY ATTEMPTS TO SEND
THE COMMAND SQUELCH POS TO THE PK-232. WITH RELEASE 25 JUNE 1987
FIRMWARE, ALLOWED VALUES FOR THE SQUELCH PARAMETER ARE ON, OFF, OR
NEG. THE VALUE POS CAUSES THE PK-232 TO RETURN AN ERROR CODE TO THE
PROGRAM, WHICH THEN ABRUPTLY CRASHES.
.
FORTUNATELY, THE FIX FOR THIS BUG IS SIMPLE. IT IS ONLY NECESSARY
TO CHANGE THE PROGRAM TO SEND THE ALLOWABLE VALUES FOR THE SQUELCH
PARAMETER TO THE PK-232. THE PATCH BELOW WILL REPLACE THE PROGRAM
VALUES OF NEG AND POS WITH OFF AND ON RESPECTIVELY.
