Pass Xon
The Pass Xon parameter enables the XON/XOFF flow control signals to be
passed on to the data device. This option has to be used in conjunction with
the software-based XON/XOFF flow control option. The default condition is
for this option to be turned off, and normally it should remain off.
Echo
The Echo parameter enables data entered on the data device keyboard to
be returned to the device's monitor. The purpose of this option is so that an
operator will not experience undue delays in seeing entered data appear
on their monitor. The default condition for the echo option is off.
EIA Pass Through
The EIA Pass Through parameter allows the data device to receive EIA
control signals through the MultiFRAD. Since, in normal interactive oper-
ation, the existence of a MultiFRAD should be transparent to the user, the
EIA pass through option allows a terminal to operate as if it were connected
directly to a communications line and not through a MultiFRAD. This is done
by allowing selected pins (signals) on one MultiFRAD to be passed through
to selected pins on a remote MultiFRAD. The default condition is for this
option to be turned off. The following diagram shows how the EIA pass
through option routes the selected signals:
