Got the commands working. Deleted the "00 Don't care value" shown in the ICD.

Same problem with commands 02 and 03 to change RX/IC volume, and commands 05 and 06 to change squelch. Values are not changing. Byte sequence for command 02, for example, is
0x02 0x05 0x02 0x00 0x57
0x57 is = 0x02^0x55
Any suggestions would be greatly appreciated. Thanks.

No joy. I can write the active and standby frequencies individually, with commands 00 and 01, so I know the serial port link is working. I've verified the byte sequence and that the sequence is being written for the command to flip frequencies. Not sure what else to try.

Trying to flip active and standby frequencies in the V16. I send byte sequence
0x02,0x05,0x12,0x00,0x12^0x55
which appears to be correct from the V16 ICD. But the frequencies do not flip. What am I doing wrong?
Thanks.
