Strip parity when sending data to the host
Enabling this parameter causes the router to remove any parity before sending the data to the
host.
Force parity when sending data to the host
If enabled, the router always uses EVEN parity when relaying data from the locally connected
TPAD terminal to the remote host. To allow data to pass through without the parity being
changed disable this setting.
Strip Trailing Spaces
If enabled, the TPAD instance looks at responses coming from the host and remove any trailing
space characters from the end of the packet before relaying the data to the terminal. This may
be necessary if the host system pads out responses with unnecessary spaces which can cause
abnormal behavior in some terminals.
Acknowledge TPAD data packets
Causes the router to acknowledge TPAD data packets from the terminal. This parameter should
normally be enabled. Use only if no polling characters (see above) are defined.
Convert leading STX character to SOH
If enabled, the router converts the leading STX character in a transaction to an SOH character.
Terminate TPAD call is EOT only
A TPAD call is normally terminated with a DLE EOT sequence. Some terminals only require the
EOT character on its own. If this is the case then enable this parameter.
Clear TPAD call if there is no response to a TPAD transaction request for x seconds
The length of time, in seconds, the router waits for a response to a TPAD transaction request
before clearing the TPAD call.
Generate an event when a TPAD transaction takes longer than x seconds
Setting this parameter to a non-zero value causes the router to generate an
Excessive Transaction Time event (code 56) each time a TPAD transaction takes longer that
the specified number of seconds. You can use this setting with an appropriate Event Handler
configuration to generate email alert messages or SNMP traps when TPAD transactions take
longer than expected. See Configuration > Alarms > Event Logcodes for a complete list of
events.
When the transaction time exceeds x milliseconds, increment the "SLA Exceptions"
statistic
When the total transaction time exceeds the value (in ms) set in this parameter, the NB SLA
exceptions statistic on the Diagnostics - Statistics > TPAD page is incremented. This statistic
can be viewed on the CLI interface by entering the at\mibs=tpad.n.stats command, where n is
the TPAD instance.
