ALTER SUBDEVICE Command
token must be present in the command, and duplicate occurrences are not
allowed.
There is a field in ZX25-MAP-ALTER-SU for each subdevice attribute that can be
altered by the ALTER SUBDEVICE command. If a field of this token is assigned a
value other than its null value, the ALTER SUBDEVICE command assigns that
value to the attribute corresponding to that field. If no value is assigned to a field,
the corresponding attribute is not altered.
ZX25-MAP-ALTER-SU contains the following fields:
ZDEV-TYPE
is a pair of integers that specifies the device type and subtype of the
subdevice. The first integer is the device type, which depends on the protocol
being used. The second integer is the subtype, which depends on the protocol
and terminal being represented. ZDEV-TYPE is required and must be assigned
one of the following pairs of integers:.
ZPROTO
specifies the protocol to be used by the subdevice. This field is required and
must be assigned one of the following values:
ZREC-SIZE
specifies the maximum length in bytes of records sent or received by the
subdevice. This field is required and must be assigned a value in the range 0
through 4095.
(6,0) The subdevice is an Interactive Terminal Interface (ITI) conversational-
mode terminal; it cannot be changed to block mode
(6,1) The subdevice is an ITI 6510 (ADM-2) terminal.
(6,2) The subdevice is an ITI 6520 (Zentec) terminal.
(6,4) The subdevice is an ITI 6530 (HP) terminal.
(9,0) The subdevice is a Process-to-Process (PTP) subdevice.
(63,0) The subdevice is a Network Access Method (NAM) subdevice.
ZX25-VAL-PROTO-ITI The Interactive Terminal Interface (ITI) protocol
will be used.
ZX25-VAL-PROTO-NAM The Network Access Method (NAM) protocol will
be used.
ZX25-VAL-PROTO-PTP The Process-to-Process (PTP) will be used.
