Considerations for the CHECK Command
If the SU being queried supports an ACSE association and therefore also a presentation 
connection and session connection, all information documented above is displayed.
If the SU being queried supports a presentation connection and therefore also a session 
connection but is not using ACSE, all information documented above except the ACSE 
portion is displayed.
If the SU being queried supports a session connection but is not using the Presentation 
Layer or ACSE, all information documented above except the ACSE and presentation 
portions is displayed.
Considerations for the CHECK Command
The considerations contain information about command use that should be read before 
studying the command syntax in too much detail.
SU Object
•
Wild cards are supported for the CHECK SU command.
•
There are a number of options to this command that can help find the particular SU 
in question:
If the SU name is not known, wild cards can be used:  specify the su-name (in the 
object-spec) with a wild card character. For example:
CHECK SU $TSP1.*
Or to find an SU in error being used by the application $TSAPP and the name of the 
TSP server then the following command will display a list of SUs:
CHECK SU $TSP1.* , OPENER $TSAPP, ERRORONLY
Or if the local TSEL used to create the connection is known, this command can be 
used:
CHECK SU $TSP1.* , LOCALTSEL "700001"
Once the command has found a particular TSP SU that matches the criteria, it will 
find the NSP SU being used by the TSP SU, and print out information about it. It 
will also check if the TSP user is OSI/AS and if so it will print out information 
about the TAPS SU.
•
The display will include the TAPS SU information only if the user of the TSP SU is 
a TAPS process.
•
Depending on the state of the TSP SU and the error situation, the NSP LINE 
information may or may not be available for display. If the information is not 
available, the following line will be displayed: " NSP: unavailable "
•
The CHECK SU command will not work with a TSP process from the C21 (or 
previous) product version; an error message will be returned. Also, if the CHECK
