TXOK(1) XR32 REFERENCE MANUAL 12/2/2013
COMMAND
TXOK -- Display / Set "ok to tx" for a port.
SYNOPSIS
TXO[k] <port> [0 - 3]
DESCRIPTION
Displays the current TXOK flag setting for a port, and allows
it to be changed. This flag controls whether or not the
transmitter is allowed to key up, and whether or not the
receiver is enabled.
If two numeric arguments are supplied, the TXOK flag is set to
the second argument, otherwise the current setting for the
specified port is displayed.
Values are: 0 = TX disabled, RX enabled
1 = TX enabled, RX enabled
2 = TX disabled, RX disabled
3 = TX enabled, RX disabled
State 2 would typically be used to disable all traffic on a
port, to time out troublesome connections, or to do tests.
By default, all ports have this flag set to 1 (TX and RX
enabled).
Modified settings remain in force until changed or system is
restarted.
EXAMPLE
TXOK 3 - Display current setting for port 3
TXOK 3 0 - Stop port 3 transmissions.
AVAILABILITY
Requires SYSOP status.
CAVEATS
It should be obvious, but if you set TXOK=0 for the port you
are using to send commands, you will lose control of the node!
NOTES
Setting TXOK=0 does not actually disable the transmitter
itself, it merely prevents any frames being sent to the TNC,
so if the latter has a built-in CWID, it will still key up the
TX so send the CWID.
