Using the DeviceManager 63
Configuring Lines
Terminal Type
Specifies the type of terminal connected to the line:
z
Dumb
z WYSE60
z
VT100
z
ANSI
z
TVI925
z IBM3151TE
z
VT320 (specifically supporting VT320-7)
z
HP700 (specifically supporting HP700/44)
z Term1, Term2, Term3 (user defined terminals)
Serial Interface
Specifies the type of line that is being used with the Terminal Server. Select
either
EIA-232 , EIA-422 , or EIA-485 .
Speed
Specifies the baud rate of the line; keep in mind that speed is affected by
the length of the cable.
Bits
Specifies the number of bits in a byte. The default is
8
.
Parity
Specifies if you are using Even , Odd , or No parity on the line. If you want to
force a parity type, you can specify Mark for 1or Space for 0.
Stop Bits
Specifies the number of stop bits that follow a byte.
Flow Control
Defines whether the data flow is handled by the software (
Soft
), hardware
( Hard ), Both , or None .
Single Character
Interrupt
When enabled, causes the Terminal Server to process every character as it
comes in, as opposed to buffering the characters before processing; this
provides better latency at the expense of efficiency.
Duplex
Specify whether the line is Full Duplex (communication both ways at the
same time) or Half Duplex (communication in one direction at a time).
TX Driver Control
Used with a
EIA-485
serial interface, if your application supports
RTS
(Request To Send), select this option. Otherwise, select
Auto
. Default is
Auto .
Echo Suppression
This parameter applies only to EIA-485 Half Duplex mode. All characters
will be echoed to the user and transmitted across the serial ports. Some
EIA-485 applications require local echo to be enabled in order to monitor
the loopback data to determine that line contention has occurred. If your
application cannot handle loopback data, echo suppression should be
On .
The default is echo suppression
Off
.
Monitor DSR
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 Terminal Server detects a DSR signal,
the line service is started. Default is
Off
. If both
Monitor DCD
and
Monitor
DSR
are enabled, both signals must be detected before the line service is
started.
Monitor DCD
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 Terminal Server detects a DCD signal,
the line service is started. Default is
Off . If both Monitor DCD and Monitor
DSR are enabled, both signals must be detected before the line service is
started.
