<strong>PK</strong>-<strong>232</strong> OPERATING MANUAL<br />
COMMAND SUMMARY<br />
Vhf ON/OFF<br />
Mode: Packet<br />
Parameters:<br />
Default: ON<br />
Host: VH<br />
ON — Packet tones are shifted 1000 Hz.<br />
OFF — Packet tones are shifted 200 Hz.<br />
Use the VHF Command for immediate software control of the <strong>PK</strong>-<strong>232</strong>'s modem tones.<br />
Changing components or switch settings is not required.<br />
Set VHF ON for VHF operation (default), and set VHF OFF for HF packet operation.<br />
NOTE: Be sure to change HBAUD to 300 bauds when operating below 28 MHz.<br />
WHYnot ON/OFF<br />
Mode: Packet<br />
Parameters:<br />
Default: OFF<br />
Host: WN<br />
ON — The <strong>PK</strong>-<strong>232</strong> generates a reason why received packets were not<br />
displayed.<br />
OFF — This function is disabled.<br />
During packet operation, the <strong>PK</strong>-<strong>232</strong> may receive many packets that are not<br />
displayed. Turning WHYNOT on will cause the <strong>PK</strong>-<strong>232</strong> to display a message<br />
explaining the reason the received packet was not displayed to the screen. The<br />
messages and their meanings are shown below:<br />
PASSALL:<br />
DCD Threshold:<br />
MONITOR:<br />
MCON:<br />
MPROTO:<br />
MFROM/MTO:<br />
<strong>MBX</strong>:<br />
<strong>MBX</strong> Sequence:<br />
Frame too long:<br />
Frame too short:<br />
RX overrun:<br />
The received packet frame had errors, and PASSALL was off,<br />
preventing the packet from being displayed to the screen.<br />
The Threshold control was set too far counter clockwise. The<br />
DCO LED was off when the packet was received.<br />
The MONITOR value was set too low to receive this frame.<br />
MCON was set too low to receive this type of frame.<br />
MPROTO was set to off, and the received packet was probably a<br />
NET/ROM or TCP/IP frame.<br />
The frame was blocked by the MFROM or MTO command.<br />
The call sign of the sending station does not match the call<br />
sign setting in the <strong>MBX</strong> command.<br />
The frame was received out of sequence, probably a retry.<br />
Incoming packet frame longer than 330 bytes. Probably a non-<br />
AX.25 frame.<br />
Incoming packet frame shorter than 15 bytes. Only seen if<br />
PASSALL ON. Probably noise.<br />
Another HDLC byte was received before we could read the<br />
previous one out of the HDLC chip.<br />
