Session Strings Controls the sending of ASCII strings to serial devices at session start and
session termination 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. Non printable ascii characters
must be entered in this format <027>. The decimal numbers within the
brackets must be 3 digits long (example 003 not 3).
z Send at End - If configured, this string will be sent to the serial device
when the TCP session on the LAN is terminated. If multihost is
configured, this string will only be send in listen mode to the serial device
when all multihost connections are terminated.
Range: 0-127 alpha-numeric characters. Non printable ascii characters
must be entered in this format <027>. The decimal numbers within the
brackets must be 3 digits long (example 003 not 3).
z Delay after Send—If configured, a delay time 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.
Range: 0-65535 ms
Default: 10 ms
