reverse slant EO Since the 3277 logical tab value X'61' is now a displayed
character on the 3278 Model 21, the tab function is changed to allow
the operator to specify another character as the logical tab. This
is done through the use of a new operand of the TERMINAL command.
The ney operand and its parameters are TIBCHAR The
operator may also query the setting of the logical tab via the QUERY TERMINAL command. CP returns as part of its response to the command,
TABCHAR {ONIOFFlchar}. • Keyboard changes. The REQ and CNCL keys On the 3278 Model 2A perform
the same functions as the PAl and PA2 keys on the 3277. No PA3 and
CLEAR keys exist on the 3278 Model 21. When generating the device type for the 3278 Model 2A, specify DEVTYPE=3278 and MODEL=2A in the RDEVICE macrc instruction and the CUTYPE=3272 in the RCTLUHIT macro instruction.
The 3287 Model 1 or 2 printer is used with the 4331 and 4341 processors as the system hardcopy device. When generating the device
type for the 3287 Model 1 or 2, specify DEVTYPE=3287 in the RDEVICE macro instruction.

3203 Model 5 Printer Support
The 3203 Model 5 printer is a channel attached version of the 3203 "odel 4 printer. VM/370 supports the new model in the same way that it
supports the Model 4 Note that the DEVTYPE=3203 and BODEL=5 operands of the RDEVICE macro instruction must be specified to generate
support of the device.
