CBLDCMCF('TACTCN ') establishes connection.

Normal termination of CBLDCMCF('TACTCN ') indicates that the connection establishment request was accepted successfully by the protocol product. However, this does not necessarily mean that connection with the remote system has been established.

If you intend to perform any connection-related operation after calling CBLDCMCF('TACTCN '), first use CBLDCMCF('TLSCN ') to check the connection status.

data-name-A

Specify VALUE 'TACTCN' for the request code indicating connection establishment.

data-name-C

Specify how to specify the connection that is to be established.

'LE'

Specifies that a logical terminal name is specified for the connection that is to be established. This argument is not supported by TP1/NET/NCSB or TP1/NET/X25-Extended.

'CN'

Specifies that a connection ID is specified for the connection that is to be established.

Space

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

data-name-D1

Specify a space.

data-name-D2

Specifies whether functionality that depends on the communication protocol is being used.

'1'

Specifies that functionality that depends on the communication protocol is being used.

'0'

Specifies that functionality that depends on the communication protocol is not being used.

Space

'0' (functionality that depends on the communication protocol is not being used) is assumed.

data-name-D3

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 establishment.

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 that is to be established. 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-K1

Specify the length of a protocol-specific area. You can specify a maximum of 1024 bytes.

If you do not use functionality that depends on the communication protocol, specify 0.

data-name-K2

Specify contents for the protocol-specific area.

The permitted value depends on the communication protocol being used. For details, see the applicable OpenTP1 Protocol manual.

data-name-L

Specify 0.

data-name-B

A status code of 5 digits is returned.

Status code	Explanation
00000	Normal termination.
71001	CBLDCMCF('TACTCN ') cannot be accepted because MCF is under start processing.
71002	CBLDCMCF('TACTCN ') cannot be accepted because MCF is under termination processing.
71004	A memory shortage occurred during CBLDCMCF('TACTCN ') 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.
71007	The specified connection name has not been registered.
71008	The specified logical terminal name has not been registered.
71009	CBLDCMCF('TACTCN ') is not supported by the applicable communication process.
71010	Although the request to establish connection was issued to the MCF communication process, the request was not accepted. For the cause, see the message log file.
71011	CBLDCMCF('TACTCN ') 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	<If '0' or a space is specified for data-name-D2> A nonzero value is specified for data-name-K1.
	<If '1' is specified for data-name-D2> A value smaller than 0 or greater than 1024 is specified for data-name-K1.
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-D1 or data-name-D3 is not a space.
	The value specified for data-name-D2 is not 1, 0, or a space.
72061	A value smaller than 0 or greater than 239 is specified for data-name-E.
72063	A space is specified for data-name-F1.
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.
