The Purpose of this program is that you can check if you have your
cdrom/scanner or other scsi device turned on. This program give a
standard RETURN_OK or RETURN_FAIL/RETURN_WARN return value. Based on
that you can perform some conditional actions, like mounting when the
device is available, etc. I mount my devices from DEVS:DosDrivers, but
when I forgot to turn my CDROM on I always got a lot of problems. So
when I didn't want my CDROM to be mounted, I had to move the MountFile
CD0 to SYS:Storage/DosDrivers. See the next snippet of my startup-sequence
to get the general Idea of this program
snippet of my startup-sequence!
ExistsSCSIDEV DEVICE scsi.device UNIT 2 TYPE CDROM
IF NOT WARN
Copy SYS1:Storage/DosDrivers/CD0 devs:DosDrivers QUIET
Copy SYS1:Storage/DosDrivers/CD0.info devs:DosDrivers QUIET
EndIf
IF EXISTS SYS:Devs/DOSDrivers
Mount >NIL: SYS:Devs/DosDrivers/~(#?.info)
EndIF
IF EXISTS Devs:DosDrivers/CD0
Delete Devs:DosDrivers/CD0 Devs:DosDrivers/CD0.info QUIET
EndIf
Change Moumtfile name to the one you use, or if you mount directly
from Mountlist you have to do the mounting where I do the copying.
Usage:
ExistsSCSIDEV DEVICE/K,UNIT/K/N,TYPE/K,VERBOSE/S,HELP/S
Example:
ExistsSCSIDEV DEVICE scsi.device UNIT 2 TYPE CDROM VERBOSE HELP
valid TYPEs are:
DIRECT, SEQUENTIAL, PRINTER, CPU, WRITEONCE, CDROM,
SCANNER, OPTICALMEM, MEDIUMCHGR, COMM, ASC1IT8, ASC2IT8,
RESERVED1, RESERVED2, RESERVED3, RESERVED4, RESERVED5, RESERVED6,
RESERVED7, RESERVED8, RESERVED9, RESERVED10, RESERVED11, RESERVED12,
RESERVED13, RESERVED14, RESERVED15, RESERVED16, RESERVED17, RESERVED18,
RESERVED19, UNKNOWN,
VERBOSE gives out extra information. If you don't know what type your
device is, you will get information about the type which was found.
SCSI-2 Compiliant Device <-- SCSI-1 or SCSI-2 device type
Wanted Device: CD-ROM device <-- Description of the wanted device type
Parsed Type Argument: CDROM <-- Here you find the wanted device type
Actual Device Found: CD-ROM device <-- Description of the found device type
Required Type Argument: CDROM <-- Here you find the found device type
SANYO CRD-250S Rev:1.19 <-- Inquiry Data from found device
I didn't do any programming on the Amiga for several years. I started
looking at my Amiga a week ago. And I'm pleased with the ease of use and
the clear way to program for the Amiga.
I programmed almost a decade for the Windows environment, which is a very
closed system. It is a shame that the Amiga didn't do better than it.
