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 param eters:
Signals high
when... This option has the following impact based on the state of the TruePort connection:
zTruePort Lite Mode—When enabled, the EIA-232 signals remain active
before, during, and after the TruePort connection is established. When
disabled, the EIA-232 si gnals remain inactive when there is no T ruePort
connection and active when there is a TruePort connection.
zTruePort 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 T ruePort 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 netwo rk 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
