Epson Multi-mode Data Controller MFJ-1278B - Manual (Page 282)

MFJ-1278B MULTI-MODE OPERATIONAL COMMANDS
TRANS Mode: Packet Immediate Command
This is an immediate command. It causes the MFJ-1278B to exit from Command Mode into
Transparent Mode. The current link state is not affected.
Transparent Mode is primarily useful for computer communications. In this mode, the
"human interface" features such as input editing capability, echoing of input characters, and
type-in flow control are disabled. You may find Transparent Mode useful for computer
Bulletin Board operations or for transferring non-text files. See the discussion of Transparent
Mode in Chapter 5.
TRFLOW ON/OFF
Mode:Packet Default: OFF
Parameters:
ON
Software flow control can be enabled for the computer or terminal in Transparent
Mode.
OFF
Software flow control is disabled for the computer or terminal in Transparent
Mode.
If TRFLOW is ON, the settings of START and STOP are used to determine the type of
flow control used in Transparent Mode. If TRFLOW is OFF, only hardware flow control is
available to the computer and all characters received by the MFJ-1278B are transmitted as
data. If START and STOP are set to $00, disabling the User Stop and User Restart
characters, hardware flow control must always be used by the computer.
If TRFLOW is ON, and START and STOP are non-zero, software flow control is enabled
for the user's computer or terminal. The MFJ-1278B will respond to the User's Restart and
User's Stop characters (set by START and STOP) while remaining transparent to all other
characters from the terminal. Unless TXFLOW is also ON, only hardware flow control is
available to the MFJ-1278B to control output from the terminal.
