Changes the amount of time the MSS will allow serial characters to accumulate before sending them to the host. Several different triggers can be used to notify the MSS when to send the accumulated data. You can specify a “timeout” condition of either the time since the last character was received (the Timeout Idle parameter) or the time since the current “character burst” was started (the Timeout Frame parameters). The timer resolution on the MSS is approximately 20 milliseconds. Any timeout values lower than 30 milliseconds will be approximated as well as possible.

Another option is to set a one- or two-character trigger, specified through the Character parameter, that will cause the MSS to transmit the data. You can also specify whether the trigger characters will be sent to the host as part of the serial data or whether they should be discarded through the Save parameter.

Packets created by the serial handling rules will be queued to the ethernet driver as a single operation, but there is no guarantee that they will be received at the host in a single network read. If the serial input buffer is filled, the accumulated data will be queued to the ethernet driver regardless of the serial handling rules. The serial input buffer size is 1024 bytes.

Restrictions Requires privileged user status.

ParametersPort

MSS4 only. Specifies a particular port or group of ports.

Note: In the absence of the PortList parameter, the configuration will affect the MSS4’s current port only.

PortList

Specify a particular port or group of ports. Port numbers are specified with integers between 1 and 4, and should be separated with commas (for lists) or dashes (for ranges).
