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 and WP-Graphics mode, 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 

 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
