Serial Port Profiles
134 IOLAN SDS/SCS/STS/MDC User’s Guide, Version 4.0
Advanced Tab Field Descriptions
The TruePort Advanced tab determines how the TruePort connection is initiated and then sets up the
appropriate connection parameters.
Configure the following parameters:
Signals high
when...
This option has the following impact based on the state of the TruePort
connection:
z TruePort Lite Mode—When enabled, the EIA-232 signals remain active
before, during, and after the TruePort connection is established. When
disabled, the EIA-232 signals remain inactive when there is no TruePort
connection and active when there is a TruePort connection.
z TruePort Full Mode—When enabled, the EIA-232 signals remain active
before and after the TruePort connection and the TruePort client will
control the state of the signals during the established TruePort connection.
When disabled, the EIA-232 signals remain inactive before and after the
TruePort connection and the TruePort client will control the state of the
signals during the established TruePort connection.
Default: Enabled
Enable Message of
the Day (MOTD)
Enables/disables the display of the message of the day.
Default: Disabled
Enable TCP
Keepalive
Enables a per-connection TCP keepalive feature. After the configured number
of seconds, the connection will send a gratuitous ACK to the network peer,
thus either ensuring the connection stays active OR causing a dropped
connection condition to be recognized.
This parameter needs to be used in conjunction with
Monitor Connection
Status Interval
parameter found in the Serial, Advanced, Advanced Settings
tab. The interval specifies the inactivity period before "testing" the connection.
Default: Disabled
