Epson Multi-mode Data Controller MFJ-1278B - Manual (Page 289)

MFJ-1278B MULTI-MODE OPERATIONAL COMMANDS
TXFLOW ON/OFF Mode: All Default: OFF
Parameters:
ON
Software flow control can be enabled for the MFJ-1278B in Transparent Mode.
OFF
Software flow control is disabled for the MFJ-1278B in Transparent Mode.
If TXFLOW is ON, the setting of XFLOW is used to determine the type of flow control
used in Transparent Mode. If TXFLOW is OFF, the MFJ-1278B will use only hardware
flow control and all data sent to the terminal remains fully transparent.
If TXFLOW and XFLOW are ON, the MFJ-1278B will use the MFJ-1278B Restart and
MFJ-1278B Stop characters (set by XON and XOFF) to control input from the terminal.
Unless TRFLOW is also ON, only hardware flow control is available to the computer or
terminal to control output from the MFJ-1278B.
Note that if the MFJ-1278B Restart and Stop characters are set to $00, hardware flow
control will always be selected regardless of the setting of TXFLOW.
TXINVERT ON/OFF
Mode: RTTY/ASCII Default: OFF
When the TXINVERT command is ON, the transmitted RTTY/ASCII data by the MFJ-
1278B is sent inverted, i.e. the marks are sent as spaces and vice versa.
TXTMO n
Mode: Packet Default: 0
Parameters:
n = 0 - 65535
TXTMO is a HEALTH counter that registers the number of packet transmitter
timeout/recovery events that have occurred since the MFJ-1278B was powered up.
