lastcphelp START TRANSPORT — VMS PCSA_Server_2.1
Format: START TRANSPORT /qualifier
Start LASTDRIVER. By default, LASTCP will initialize the first
ethernet controller for LASTDRIVER.
The LAST transport should not be started until after DECnet has been
started. If the LAST transport is started before DECnet, DECnet will
fail to start properly.

/CIRCUIT_MAXIMUM/GROUP/CHECKSUM/CONTROLLERS
/ALL_CONTROLLERS/TRANSMIT_QUOTA/SLOW_MODE/NODE_NAME
/CIRCUIT_MAXIMUM
Format: START TRANSPORT /CIRCUIT_MAXIMUM=n
Set the maximum number of nodes that may simultaneously be connected.
The default maximum circuits is 80.
/GROUP
Format: START TRANSPORT /GROUP=n
Grouping is a method for segmenting LANs such that services associated with
certain nodes will not be by seen by other nodes. An example of such an
environment would be an extended LAN. Here, a network manager may wish
to restrict nodes to services offered on their own LAN segment.
When specifying a group, the user should enter a number between 0 and 1023
inclusive. The default group is group zero.
/CHECKSUM
Format: START TRANSPORT /CHECKSUM
Establish mandatory data checksumming for all messages exchanged
between the current node and any remote node. LASTDRIVER computes a
checksum for all messages, and verifies the checksum on all received
messages.
/CONTROLLERS
Format: START TRANSPORT /CONTROLLERS=([{controller letter,}...])
This qualifier allows the user to specify which Ethernet controllers
are to be initialized for LASTDRIVER. The default is to initialize the
first ethernet controller.
This qualifier may not be used if the /ALL_ETHERNET qualifier is used.

examples
START TRANSPORT /CONTROLLERS=(A,B) This command instructs LASTCP to initialize controllers A and B with the LAST protocol. START TRANSPORT /CONTROLLERS=B This command instructs LASTCP to initialize controller B with the LAST protocol.
unit-names
A unit name is of the form DDCU: where DD is the device type C is the controller field U is the unit number When specifying controllers for LASTDRIVER use the controller field of the unit name. XQA0 is controller A XEB0 is controller B
/ALL_CONTROLLERS
Format: START TRANSPORT /ALL_CONTROLLERS
This qualifier instructs LASTCP to start the LAST protocol on all
Ethernet adapters available.
This qualifier may not be used if the /CONTROLLERS qualifier is
used.
The default is to start only the first ethernet controller.
/TRANSMIT_QUOTA
Format: START TRANSPORT /TRANSMIT_QUOTA=n
This qualifier establishes the number of transmit buffers LASTDRIVER
may use to communicate with a remote node.
The default is to use 5 transmit buffers.
/SLOW_MODE
Format: START TRANSPORT /SLOW_MODE
This qualifier instructs LASTDRIVER to require remote transmitters to
use a TRANSMIT_QUOTA of 1 when communicating with this node.
This qualifier is not normally used.
/NODE_NAME
Format: START TRANSPORT /NODE_NAME=name
This qualifier instructs LASTCP to initialize LASTDRIVER with the node
name specified.
If not specified, LASTCP will use the DECnet node name.
