Serial Port Profiles
Enable Data 
Logging
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.  If using the Trueport profile, data logging is only supported in Lite 
Mode.
The minimum data buffer size for all models is 1 KB. The maximum data 
buffer size is 2000 KB for DS1/TS2/STS8D, all other models are 4000 KB.  If 
the data buffer is filled, incoming serial data will overwrite the oldest data.
Values: 1-2000 KB (DS1/TS1/STS8D) - Default 4 KB
Values: 1-4000 KB (all other models) - Default 256 KB
Default: Disabled
Note: A kill line or a reboot of the IOLAN causes all buffered data to be 
lost
.
Some profile features are not compatible with the data logging feature. See 
.
To change the default data logging buffer size see 
.
Idle Timeout
Use this timer to close a connection because of inactivity. When the 
Idle 
Timeout
 expires, the IOLAN will end the connection. 
Range: 0-4294967 seconds (about 49 days)
Default: 
0
 seconds so the port will never timeout
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 device 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.
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
