CBLDCMCF('TLSCN ') acquires the status of a connection.

data-name-A

Specify VALUE 'TLSCN' for the request code indicating connection status acquisition.

data-name-C

Specifies how to specify the connection whose status is to be acquired.

'LE'

Specifies that a logical terminal name is specified for the connection whose status is to be acquired. This value cannot be specified for TP1/NET/NCSB or TP1/NET/X25-Extended.

'CN'

Specifies that a connection ID is specified for the connection whose status is to be acquired.

Space

'LE' (specification of a logical terminal name) is assumed.

data-name-D

Specify a space.

data-name-E

Specify the MCF communication process identifier of the MCF communication service for the connection that is to be processed. The permitted value range is from 0 to 239.

This argument is ignored when a logical terminal name is used to request connection status acquisition.

If you specify 0, the system searches for the MCF communication service to which the specified connection ID belongs. In a configuration where many MCF communication services are running or when you issue this function many times from a UAP, we recommend that you specify the MCF communication process identifier.

data-name-F1

Specify the logical terminal name or connection ID of the connection whose status is to be acquired. Express the logical terminal name or connection ID as a maximum of 8 bytes. If the specified name is shorter than 8 bytes, pad the name with trailing spaces.

data-name-F2, data-name-G, data-name-H, data-name-I, data-name-J

Specify a space.

data-name-K, data-name-L

Specify 0.

data-name-M

Specify 1 as the number of unique names from unique-name-4 to unique-name-n (number of sets of data-name-N, data-name-O, data-name-P, and data-name-Q).

When the processing is completed, the number of corresponding connections is returned.

data-name-Q

This is an area used by MCF.

data-name-B

A status code of 5 digits is returned.

data-name-M

Returns the number of connections that were processed by this function.

data-name-N

Sets the connection ID of the requested connection.

data-name-O

Sets one of the following values as the protocol type of the requested connection:

'UA'

TP1/NET/User Agent (OSAS/UA protocol)

'hds'

TP1/NET/HDLC (HDLC protocol)

'X25'

TP1/NET/X25 (X.25 protocol)

'TP'

TP1/NET/OSI-TP (OSI TP protocol)

'XP'

TP1/NET/XMAP3

'HS1'

TP1/NET/HSC (HSC1 protocol)

'HS2'

TP1/NET/HSC (HSC2 protocol)

'CSB'

TP1/NET/NCSB (NCSB protocol)

'NIF'

TP1/NET/OSAS-NIF (NIF/OSI protocol)

'SL2'

TP1/NET/Secondary Logical Unit - TypeP2 (SLUTYPE-P protocol (secondary station))

'TCP'

TP1/NET/TCP/IP (TCP/IP protocol)

'X2E'

TP1/NET/X25-Extended (X.25 protocol)

data-name-P

Sets one of the following values as the status of the requested connection:

'ACT'

Connection has been established.

'ACTB'

Connection establishment processing is under way.

'DCT'

Connection has been released.

'DCTB'

Connection release processing is under way.

Status code	Explanation
00000	Normal termination.
71001	CBLDCMCF('TLSCN ') cannot be accepted because MCF is under start processing.
71004	A memory shortage occurred during CBLDCMCF('TLSCN ') processing.
71005	A communication error occurred. For the cause, see the message log file.
71006	An internal error occurred. For the cause, see the message log file.

71008	The specified logical terminal name has not been registered.
71009	CBLDCMCF('TLSCN ') is not supported by the applicable communication process.
71010	Although the request to acquire the connection status was issued to the MCF communication process, the request was not accepted. For the cause, see the message log file.
71011	CBLDCMCF('TLSCN ') cannot be accepted because the connection has been deleted.
71014	The specified logical terminal name belongs to TP1/NET/NCSB or TP1/NET/X25-Extended; or, the specified connection group name belongs to TP1/NET/OSI-TP or TP1/NET/TCP/IP.
72028	The value specified for data-name-A is invalid.
72052	A nonzero value is specified for data-name-K.
72053	A nonzero value is specified for data-name-L.
72058	The value specified for data-name-C is not 'LE', 'CN', or a space.
72059	The value specified for data-name-D is not a space.
72061	A value smaller than 0 or greater than 239 is specified for data-name-E.
72063	data-name-F1 begins with a space.
72065	The value specified for data-name-F2 is not a space.
72066	The value specified for data-name-G is not a space.
72068	The value specified for data-name-H is not a space.
72070	The value specified for data-name-I is not a space.
72072	The value specified for data-name-J is not a space.
72074	The character string specified for data-name-F1 contains an invalid character.
72076	The value 1 is not specified for data-name-M.
