Serial Port Profiles
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
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
Default: None
Enable Inbound
Flow Control
Determines if input flow control is to be used.
Default: Enabled
Default: Enabled
Enable Outbound
Flow Control
Flow Control
Determines if output flow control is to be used.
Default: Enabled
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
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
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
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
Default: Disabled
Discard Characters
Received with
Received with
Errors
When enabled, the IOLAN will discard characters received with a parity or
framing error.
Default: Disabled
framing error.
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
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
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
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
Default: Disabled
