Epson MFJ-1278B manual Xmitok ON/OFF, Xoff n Mode All Default $13

MFJ-1278B MULTI-MODE OPERATIONAL COMMANDS

Parameters:

ON XON/XOFF flow control is enabled.

OFF XON/XOFF flow control is disabled and hardware flow control is enabled.

If XFLOW is ON, the computer or terminal is assumed to respond to the MFJ-1278B Restart and Stop characters set by XON and XOFF. If XFLOW is OFF, the MFJ- 1278B will communicate flow control commands via RTS.

XMITOK ON/OFF Mode: Packet Default: ON

Parameters:

ON Transmit functions are enabled.

OFF Transmit functions are disabled.

When XMITOK is OFF, transmitting is inhibited. All other functions of the board remain the same, in other words, the MFJ-1278B generates and sends packets as requested, but does not key the radio PTT line.

You might use this command to insure that your MFJ-1278B does not transmit in your absence if you leave it operating to monitor packet activity. This command can also be used for testing using loopback or direct wire connections when PTT operation is not relevant.

XOFF n Mode: All Default: $13

Parameters:

n0 to $7F, specifying an ASCII character code.

This command selects the MFJ-1278B Stop character, that is sent by the MFJ-1278B to the computer or terminal to stop input from that device. You can enter the code in either hex or decimal.

This character would ordinarily be set to <CTRL-S> for computer data transfers. If you are operating your station in a Converse Mode and there is some chance that you might fill up the MFJ-1278B's buffers, you might set this character to <CTRL-G> ($07), which rings a bell on many terminals.
