Format: sda> net show tpcons
Transport Provider Connection Oriented network Service VAX
Communication module. An executable loadable image, which
is a lower VCM to OSI Transport and a user of TCP/IP stack.
This convergence layer will make TCP transport appear to be
a CONS Network Service to OSI Transport.
The number of connections displayed might not map to the
number of transport connections if OSI is using classes
{ 2, 4} due to the multiplexing of transport connections.

1 – ATBS
Format: sda> net show tpcons atbs
Show the Association Block Table and any of its
extensions tables. This table contains the
information regarding associations between transport
and TPCONS. The association table contains TPCB port
blocks. (@tpcons$ga_atb/type=atb)
2 – TPTBs
Format: sda> net show tpcons tptbs
Show the Transport Provider Association Block Table and any
of its extensions tables. This table contains the
information regarding associations between transport
and the tcp/ip provider.
The table should contain a 1-1 correspondence to TPCONS
connections. For example: if you have a single connection
looped back to your node, you will see three TPCB blocks in
the TPTB table. One for the listen port and one for each end
of the TPCONS connection for a total of three TPCB ports.

3 – TPCBS
Format: sda> net show tpcons tpcbs
A TPCB is a data structure describing a TPCONS
connection. Each Transport Provider Control Block represents
one TCP/IP connection. The existence of a TPCB block does
NOT constitute an OSI Transport Connections until a connect
initiate/accept has been requested by OSI Transport. Once
this procedure has been sucessfully accomplished, the TPCB
represents one or more OSI Transport connections over TCP/IP
depending on the OSI Transport CLASS selected - multiplexing.
4 – STATS
Format: sda> net show tpcons stats
The Statistic block holds all operations issued and
received by the TPCONS VCM. Currectly the low order
longword is displayed.
