Field

Description

LINE

Line number of the port

BAUD

Receive/Transmission Rate

PAR

Parity: Even (E), Odd (O), Mark (M), Space (S), None (N)

BITS

Number of bits

INPUT-FLOW

Type of input flow control in force:

  • XI=<ASCII hex code><ASCII hex code>

  • CTS (Clear-To-Send) Input Flow Control

OUTPUT-FLOW

Type of output flow control in force:

  • XO=<ASCII hex code><ASCII hex code>

  • DTR (Data Terminal Ready) Output Flow Control

CTS

Output level of CTS (Clear-To-Send) line is displayed: 1 if the level is high, 0 if it is low. If CTS is used as INPUT-FLOW Control, - is displayed.

DSR

Output level of DSR (Data Set Ready) line is displayed: 1 if the level is high, 0 if it is low.

BELL

If the BELL feature is enabled, the ASCII code for the BELL character is displayed. If the BELL feature is disabled, OFF is displayed.

BKEY

If an ALTERNATE BREAK KEY is defined, the ASCII code for that character is displayed. If the ALTERNATE BREAK KEY is disabled, OFF is displayed.

WRAP

The display indicates whether the type-ahead wrap feature is enabled (ON) or disabled (OFF).

PRCS

If the line is linked to a process, the process number is displayed. If the line is attached to a process, the process number is displayed along with an A. If neither of the above cases hold true, the process field is empty. A * is always displayed next to the user's process number.

 

NOTE

Characteristics primarily associated with processes may be displayed using PROCESS-STATUS (see PROCESS-STATUS Command).
