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.
