PORTS: F6 49
EIA (Aux) Xmit: [No Protocol, Xon-Xoff, DSR (DTR), Both]
This is similar to “EIA (Aux) Recv,” except that it applies to the
data transmitted from the terminal to the primary or secondary
host or printer. DSR is the hardware signal for Data Set Ready
(pin 6).
In ADDS VP emulation, DC1 and DC3 can be interpreted as
data and should not be selected as a form of protocol.
EIA (Aux) Break: [250 ms, 170 ms, 500 ms, Off]
Choose the duration of the break signal in milliseconds. This is
an interruption in data flow, and can be disabled.
EIA (Aux) Modem Control: [On, Off]
If a modem is being used to communicate with the primary or
secondary host, modem control should be on. To perform a
disconnect, the terminal drops the DTR signal. In full duplex, the
terminal keeps RTS high and checks for a CD signal before
sending data to the modem. In half duplex, it raises RTS and
awaits a clear-to-send (CTS) signal from the modem before
sending data.
EIA (Aux) Xmt Pace: [Baud, 35 cps, 60 cps, 150 cps]
Define the maximum number of characters per second that the
terminal can transmit. When a characters limit (35 cps, 60 cps, or
135 cps) is set, the delays are averaged between characters for
the selected baud rate. This is also known as “pacing.” The
Baud option provides no pacing, allowing data to be transmitted
at the specified baud rate.
EIA (Aux) Disconnect: [2sec, 60ms]
Select the maximum time period that the modem can be
disconnected (or the modem line be down) before the terminal
performs a Modem Disconnect. This occurs if “EIA (Aux) Modem
Control” is on.
