/OPEN Command

The /OPEN command restores access to terminals or line groups by the CA WA CA 7 Edition system after a /CLOSE command.

Use this command to start manually the following interfaces:

The CA WA CA 7 Edition CAICCI terminal interface
The CA WA CA 7 Edition TCP/IP terminal interface

You sometimes must start the CAICCI terminal interface manually for one of the following reasons:

CAICCI is not active when CA WA CA 7 Edition initializes.
CAICCI terminates after the interface has initialized.

To initialize the CA WA CA 7 Edition CAICCI terminal interface without recycling CA WA CA 7 Edition, use the /OPEN command specifying a GROUP that is defined as DEVICE=CCI. You do not need to issue the /OPEN for each group that is defined with DEVICE=CCI. One /OPEN issued for any such group suffices.

Do not use this command after a /CLOSE has been issued for a GROUP defined as DEVICE=CCI.

If one of the following situations occurs, you sometimes must start the TCP/IP terminal interface manually:

TCP/IP was not active when CA WA CA 7 Edition was initialized.
TCP/IP has crashed.
The TCP/IP terminal interface was shut down with a /CLOSE command.

You can initialize the TCP/IP terminal interface without recycling CA WA CA 7 Edition. Use the /OPEN command specifying any GROUP that is defined as DEVICE=CCI and the TERM=TCP/IP parameter. You do not need to issue the /OPEN for each group that is defined with DEVICE=CCI. One /OPEN issued for any such group suffices.

Format 1

This command has the following format:

/OPEN,{GROUP=group|{T|TERM}=term}

Format 2

This command has the following format:

/OPEN,GROUP=group,{T|TERM}=TCP/IP

GROUP

Defines a line group to open and identifies which group. The value must be the group name. When GROUP specifies a VTAM group, logons are accepted.

Limits: 1 to 7 alphanumeric characters

Required: Format 1: Yes (unless TERM is used). Format 2: Yes.

TERM

Specifies either the name of a VTAM terminal that is to have its logon simulated (SIMLOGON) or TCP/IP.

term: Specifies the name of the terminal. This value establishes a connection to the terminal from CA WA CA 7 Edition to VTAM.
TCP/IP: Specifies initialization of the CA WA CA 7 Edition TCP/IP terminal interface.

Limits: 1 to 7 alphanumeric characters

Required: Format 1: Yes (unless GROUP is used). Format 2: Yes.
