RTS mode. The _RtsLineRaise is defined as a long value. The valid
range is 10 - 2550 milliseconds. The Manual RTS mode has been
designed for use with radio modems.
This is a Read/Write tag.
_RtsLineDrop
Class: Parameter Tag
The _RtsLineDrop tag is a tag that allows the RTS Line to be lowered
for a user-selected period of time after the driver attempts to transmit
a message. This tag will only be effective for drivers that support
Manual RTS mode. The _RtsLineDrop is defined as a long value. The
valid range is 0 - 2550 milliseconds. The Manual RTS mode has been
designed for use with radio modems.
This is a Read/Write tag.
_RtsLinePollDelay
Class: Parameter Tag
The _RtsLinePollDelay tag is a tag that allows a user-configurable pause
to be placed after each message sent from the driver. This tag will only
be effective for drivers that support Manual RTS mode. The
_RtsLinePollDelay is defined as a long value. The valid range is 0 -
2550 milliseconds. The Manual RTS mode has been designed for use
with radio modems.
This is a Read/Write tag.
_ReportComErrors
Class: Parameter Tag
The _ReportComErrors tag is a tag that allows the reporting of low level
communications errors such as parity and framing errors to be enabled
or disabled. This tag is defined as a Boolean tag and can be set either
true or false. When true, the driver will report any low-level
communications error to the server event system. When set false the
driver will ignore the low-level communications errors and not report
them. The driver will still reject a communications transaction if it
contains errors. If the environment contains a lot of electrical noise,
this feature can be disabled to prevent the event log from filling with
error messages.
This is a Read/Write tag.
_EnableDiagnostics
Class: Parameter Tag
The _EnableDiagnostics tag is a tag that allows the diagnostic system of
the driver to be enabled and disabled. The diagnostic system places a
little additional burden on the driver while enabled. As such the server
allows diagnostics to be enabled or disabled to improve the driver's
performance. When disabled, the
will not be
available.
This is a Read/Write tag.
_WriteOptimizationDutyCycle
Class: Parameter Tag
The _WriteOptimizationDutyCycle tag is a tag that allows the duty cycle
of the Write to Read ratio to be changed on the fly. The duty cycle
controls how many Writes the driver will do for each Read it performs.
The _WriteOptimizationDutyCycle is defined as an unsigned long value.
The valid range is 1 to 10 Write per Read.

Description
_AvailableNetworkAdapters
Class: Parameter Tag
The _AvailableNetworkAdapters is a tag that lists the available NICs
and will include both unique NIC cards and NICs that have multiple IPs
assigned to them. Additionally this tag will also display any WAN
connections that are active, such as a dialup connection. This tag is
provided as a string tag and can be used to determine the network
adapters available for use on this PC. The string returned will contain all
of the NIC names and their IP assignments. A semicolon will separate
each unique NIC in order to allow the names to be parsed within an
OPC application. For a serial driver, this tag will only be used if Ethernet
