Specifications

CONNECT
CONNECT
Connects a hardware device and loads its driver, if the driver is not already
loaded.
You must have CMKRNL and SYSLCK privileges to use the CONNECT
command.
Format
IO CONNECT device-name[:]
Parameters
device-name[:]
Specifies the name of the hardware device to be connected. It should be specified
in the format device-type, controller, and unit number (for example, LPA0 where
LP is a line printer on controller A at unit number 0). If the /NOADAPTER
qualifier is specified, the device is the software device to be loaded.
Description
The CONNECT command connects a hardware device and loads its driver, if the
driver is not already loaded. You must have CMKRNL and SYSLCK privileges to
use the CONNECT command.
Qualifiers
/ADAPTER=tr_number
/NOADAPTER (default)
Specifies the nexus number of the adapter to which the specified device is
connected. It is a nonnegative 32-bit integer. /NOADAPTER indicates that
the device is not associated with any particular hardware. The /NOADAPTER
qualifier is compatible with the /DRIVER_NAME qualifier only.
/CSR=csr_address
The CSR address for the device being configured. This address must be specified
in hexadecimal. You must precede the CSR address with %X. The CSR address
is a quadword value that is loaded into IDB$Q_CSR without any interpretation
by SYSMAN. This address can be physical or virtual depending on the specific
device being connected:
• /CSR=%X3A0140120 for a physical address
• /CSR=%XFFFFFFFF807F8000 for a virtual address (the sign extension is
required for OpenVMS AXP virtual addresses)
This qualifier is required if /ADAPTER=tr_number is specified.
/DRIVER_NAME=filespec
The name of the device driver to be loaded. If this qualifier is not specified,
the default is obtained in the same manner as the SYSGEN default name.
For example, if you want to load the Digital-supplied SYS$ELDRIVER.EXE,
the ‘‘SYS$’’ must be present. Without the ‘‘SYS$’’, SYSMAN looks for
ELDRIVER.EXE in SYS$LOADABLE_IMAGES. This implementation separates
the user device driver namespace from Digital-supplied device driver namespace.
