Operation

To invoke TERMDSM enter:

   :cstm
   cstm> RU TERMDSM

At this point the system responds by displaying the TERMDSM banner, your system's Distributed Terminal Controllers and the following prompt:

Comment DIag DTc DUmp Help Reset Status EXIt ?

To proceed, select one of these eight commands by entering either the entire command or only the letters shown in upper case.

Each TERMDSM command has a security level which prevents users without certain capabilities from executing it. The following shows which capabilities are required for each of three TERMDSM security levels.

User Capability	Security Level
SM or DI	0 (greatest capability)
SM, DI or OP	1 (second most capability)
SM, DI, OP or AM	2 (least capability)

Each of the TERMDSM commands is explained on the following pages.

Comment

Comment allows comments to be entered for later reference. Security level is 2.

DIag

DIag is entered to run diagnostic functions. The system responds by displaying the following:

(diagnostics)
 
SElftest #     (DTC Selftest)
PRint    #,#,# (Print to specified port)
Internal #,#,# (Internal loopback on specified port)
EXTernal #,#,# (Loopback through hood on specified port)
Terminal #,#,# (write and read to terminal on that port)
(carriage return to exit)  ?

The parameter for SElftest is DTC number. Parameters for all other tests consist of DTC number, SIC number and port number. For example, to execute a PRint test on port 7 on SIC 0 on DTC 2 the following would be entered: PR 2,0,7.

Security level is 0 for DTC selftest; 1 for all other diagnostic tests.




	CAUTION: A DTC SElftest aborts all sessions on the DTC being tested and may result in lost data.

DUmp

DUmp dumps the contents of memory for the port and driver to disk. When DU is entered the system responds by displaying the following:

(dump)
Ldev #
POrt #,#,#
DTc #
 
(carriage return to exit)  ?

Parameters are Ldev number or DTc number. For POrt the parameters are DTC, SIC and port number. Security level is 0 for DTC dump, 1 for other functions. Ports and Ldevs are dumped to a file with the following naming convention: TRMnnnXX.pub.sys where nnn is the day of year and XX is two characters ranging from AA to ZZ. DTC's are dumped to a file named as follows: SnnnnnnX.pub.sys, where nnnnnn is the 6-digit DTC address and X ranges from A to Z. Analyzing dump contents requires specialized training and is usually done by HP support personnel.

Reset

Reset resets a DTC, SIC or port. When the Reset command is entered the system responds with the following:

(reset)
 
Ldev #
POrt #,#,#
SIc #,# (multiplexer card in DTC)
DTc #
 
(carriage return to exit)  ?

Parameters are DTC, SIC and port for POrt and DTC and SIC for SIc. Other parameters are as indicated. Security is 1 for Ldev's and ports; 0 for DTC's or SIC's.




	CAUTION: Active sessions are logged off reset devices.

Status

STatus displays information about the DTC or port. When STatus is entered the system responds by displaying:

(status)
 
DTc #
POrt #,#,#
 
(carriage return to exit)  ?

The parameter for POrt is DTC, SIC and port number.

DTc displays the system's DTC's. It provides the same information provided when TERMDSM is initiated.

Help displays informtion about TERMDSM.

EXit terminates the TERMDSM subsystem.
