Serial Port Profiles

[Trueport Lite
Mode]
When enabled, serial data will be buffered if the TCP connection is lost. When
the TCP connection is re-established, the buffered serial data will be sent to its
destination. Only valid in Trueport LITE mode. Not valid when using Trueport
in Full Mode.
The minimum data buffer size for all models is 1 KB. The maximum data
buffer is 2000 KB for the DS1/TS2/STS8D, all other models are 4000 KB. If
the data buffer is filled, incoming serial data will overwrite the oldest data.
Note: A kill line or a reboot of the IOLAN causes all buffered data to be
lost
Values: 1-2000 KB (DS1/TS2/STS8D) - default is 4 KB
Values: 1-4000 KB (all other models) - default is 256 KB
Some profile features are not compatible Data Logging. See Data Logging for
the complete list.
To change the default buffer size see Advanced Serial Settings Tab.
Idle Timeout Use this timer to close a connection because of inactivity. When the Idle
Timeout
expires, the IOLAN will end the connection.
Default:
0 seconds so the port will never timeout
Range: 0-4294967 seconds (about 49 days)
Session Timeout Use this timer to forcibly close the session/connection when the Session
Timeout expires.
Default:
0 seconds so the port will never timeout
Range: 0-4294967 seconds (about 49 days)
Session Strings Controls the sending of ASCII strings to serial devices at session start as
follows;
z Send at Start—If configured, this string will be sent to the serial device
on power-up of the IOLAN or when a kill line command is issued on this
serial port. If the "monitor DSR" or "monitor DCD" options are set, the
string will also be sent when the monitored signal is raised.
Range: 0-127 alpha-numeric characters
Range: Hexadecimal 0-FF
z Delay after Send—If configured, will inset a delay after the string is sent
to the device. This delay can be used to provide the serial device with time
to process the string before the session is initiated or terminated.
Default: 10 ms
Dial In If the device is remote and will be dialing in via modem or ISDN TA, enable
this parameter.
Default: Disabled
Dial Out If you want the modem to dial a number when the serial port is started, enable
this parameter.
Default: Disabled
Dial Timeout The number of seconds the IOLAN will wait to establish a connection to a
remote modem.
Range: 1-99
Default: 45 seconds
