8.51 DEVINIT (Reinitialize device)

8.51.1 Function

The DEVINIT command can be used to reopen an existing device. The arguments (if any) override the
arguments specified in the configuration file for this device. If no arguments (beneath the device number)
are given, then the DEVINIT command will reinitialise the device with the same arguments that were pre-
viously specified. The device type cannot be changed and must not be specified.

This command can be used to rewind a tape, to mount a new tape or disk image file on an existing de-
vice, to load a new card deck into a reader, or to close and reopen a printer or punch device.
