Serial Port Profiles
118 IOLAN SDS/SCS/STS/MDC User’s Guide, Version 4.0
Duplex Used with a EIA-485 serial interface, specify whether the serial port is Full
Duplex
(communication both ways at the same time) or Half Duplex
(communication in one direction at a time).
Default: Full
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: Auto
Flow Control Defines whether the data flow is handled by the software (Soft), hardware
(
Hard), Both, or None. If you are using SLIP, set to Hard only. If you are
using
PPP, set to either Soft or Hard (Hard is recommended). If you select
Soft with PPP, you must set the ACCM parameter when you configure PPP for
the
Serial Port.
Data Options: Soft, Hard, Both, None
Default: None
Enable Inbound
Flow Control
Determines if input flow control is to be used.
Default: Enabled
Enable Outbound
Flow Control
Determines if output flow control is to be used.
Default: Enabled
Monitor DSR Specifies whether the EIA-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 serial port
profile is started. The
Monitor DSR parameter is not available for medical unit
models. If both
Monitor DCD and Monitor DSR are enabled, both signals must
be detected before the serial port profile is started.
Default: Disabled
Monitor DCD Specifies whether the EIA-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 serial
port profile is started. If both
Monitor DCD and Monitor DSR are enabled, both
signals must be detected before the serial port profile is started.
Default: Disabled
Enable 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 enabled.
Default: Disabled
Enable Line
Termination
Used with EIA-422 and EIA-485 on SDS 8-port and 16-port rack mount
IOLAN models, specifies whether or not the line is terminated; use this option
when the serial port is connected to a device at the end of the serial network.
Default: Disabled
