Xflow; Xmitok; Xoff - Advanced Electronic Applications PK-88 Operating Manual

PK-88 OPERATING MANUAL
XFLOW ON|OFF
Parameters: ON
OFF
When XFLOW is ON, software flow control is in effect – it's assumed that the computer or terminal
will respond to the PK-88's Start and Stop characters defined by the XON and XOFF commands.
When XFLOW is OFF, the PK-88 uses hardware flow control commands on the CTS and RTS line.
For full hardware control in both directions, set XFLOW to OFF.
This type of hardware flow control is frequently required by certain host computer applications,
electronic mail and some bulletin board systems.
XMITOK ON|OFF
Parameters: ON
OFF
When XMITOK is OFF, the PTT line to your transmitter is disabled – the transmit function is inhib-
ited. All other PK-88 functions remain the same. The PK-88 generates and sends packets as re-
quested, but does not key the radio's PTT line.
Use the XMITOK command at any time to ensure that the PK-88 does not transmit.
Set XMITOK OFF if you're absent and wish to leave the PK-88 on as a channel activity monitor.
Set XMITOK OFF for testing in loopback or direct wire connections when PTT operation is not re-
quired.

XOFF

Parameters: n
Use XOFF to select the Stop character to be used to stop input from the computer or terminal.
You can enter the code in either hex or decimal.
The Stop character default value is [^S] for computer data transfers.
If you're operating in Converse Mode, and there is a chance that activity might fill the PK-88's buf-
fers, you can define the Stop character as [^G] ($07), which 'beeps' many terminals.
Mnemonic: XF
