Page of GC20-1801-10 As Updated April 1, 1981 by TNL GN25-0837 R DEVICE Macro The device types, 2540R and 2540P, refer to the same IBM 2540 Card
Read Punch (as do 1442P and 1442R, and 2520P and 2520R). Each
logical device must be specified in a separate RDEVICE macro.
In addition, any other device that can be attached to a real System/370 can be specified in the RDEVICE macro by its device
type. For unsupported devices that do not have a device type
listed under the DEVTYPE operand, you should code the subclass on
the CLASS operand. Then unsupported devices can be dedicated to a
virtual machine, and CP can log the error recordings, if there are
any. CP does not use unsupported devices for its own operations.
If a device specified in the RDEVICE macro is not supported by VM/370, the following MNOTE message (warning level) is generated: UNSUPPORTED DEVICE TYPE The device is generated as an unsupported device. An unsupported
device can only be used if it is dedicated to a virtual machine. It
is dedicated to a virtual machine if a DEDICATE control statement
is coded in the VM/370 directory for the virtual machine, or if it
is attached to it by the CP ATTACH command. Noig: If you code a 2702 device type the SETADDR value must be
specified.
MODEL=model
is the model letter and number for 3704 or 3705 or the model
number, if any, of a 2305, 3330, or 3333 device, or a tape device,
3278 display or 3203 printer. Model number, if not specified,
defaults to zero except that for the 3203 it defaults to 4. It
must be coded for 3330 devices, 3278 display, and 3203 printer. If
only a number' is coded for 3704 or 3705 devices, an MNOTE is
generated.
model is a value that can be: Device
1 or 2 2305 4 or 5 3203 1, 2, or 11 3330 1 or 11 3333 Al - H8 3704, 3705-1, or 3705-11 1, 2, 3, 4, 5, or 6 2415
5 or 7 2420 1, 2, or 3 3410 or 3411
3, 4, 5, 6, 7 or 8 3"20 1 3272 or 3274, Kodel 1B Notg§: 1. The 3277 Model 1 is a 480-character display screen and
is only supported by VM/370 as a dedicated device.
2. If a model number is included for devices that do not
require model numbers, the system generation is terminated
with an error message.
FEATURE=(feature[,feature) ••• )

A 3800 (DEVTYPE=3800) device with four Writeable Character Generation Modules For a 3330V device, either FEATURE=VIRTUAL or FEATURE=SYSVIRT must be specified. To allow CMS to correctly verify tape mode set operations, the
correct feature code for a tape device must be specified.
If the local 3277 or 3278 display device is equipped with the
optional operator identification card reader, or magnetic reader
attachment then the virtual machine operator can gain access to the
system (log on) only if he inserts a magnetically encoded card. Use the FEATURE=OPRDR operand of the RDEVICE macro to specify a 3277 or
3278 device with a card reader. If you do not want access
authorization by a card reader, do not code FEATURE=OPRDR in the RDEVICE macro. FEATURE=OPRDR is invalid if DEVTYPE=3158. Although still allowable, it is not necessary to designate FEATURE=(2CHANSW/4CHANSW) on the RDEVICE macro. DMKCPI dynamically
determines whether or not the hardware has a two-or four-channel

subclass for unsupported devices. out!!!!i Spooling The spooling classes (cl,cl ••• ) list up to four output spooling
classes separated by commas. This form of the CLASS operand can
only be specified for a 1403, 1443, or 3211 printer, or 2520P, 2540P or 3525 card punch. The spooling class, cl, is one alphameric
character. If you specify more than one class, you must separate
them by commas. If no class is specified, class A is assumed for
printers and punches. The following information should be helpful when you code this
operand: • For more information about spooling classes, see the VM/l1Q 146 IBM VM/370 Planning and System Generation Guide
