Specifies the type of line that is being used with the IOLAN. Select either EIA-232, 

EIA-422, or EIA-485 (TS2 supports only EIA-232).

Specifies whether the RS-232 signal DCD (Data Carrier Detect) should be monitored. 
This is used with modems or any other device that sends a DCD signal. When it is 

monitored and the IOLAN detects a DCD signal, the line service is started. Default is 

. If both 

 and 

 are enabled, both signals must be detected 

before the line service is started.

Specifies whether the RS-232 signal DSR (data set ready) should be monitored. This is 

used with modems or any device that sends a DSR signal. When it is monitored and the 

IOLAN detects a DSR signal, the line service is started. Default is 

. If both 

 and 

 are enabled, both signals must be detected before the line 

service is started.

Defines whether the data flow is handled by the software (

), hardware (

), 

, or 

. 

Used with a 

 serial interface, if your application supports 

 (Request To 

Send), select this option. Otherwise, select 

. Default is 

.

Specify whether the line is 

 (communication both ways at the same time) or 

 (communication in one direction at a time).
