previously specified maximum receive size, then the
new value is ignored.
• address option (code=128, length=2; 2-byte
integer) (input). (TCP only.) This option specifies the
source port address of the connection request.
Addresses in the range (octal) %74057 to %77777
can be used without special capabilities.
• facilities set name (code=142, length=8, packed
array of 8 characters) (input). For access to the X.25
protocol only. This option field is used to associate a
facilities set with the virtual circuit to be created
over an SVC. This option does not apply to a PVC.
This is an optional parameter and defaults to the
facilities set name entered while configuring the
X.25 network with NMMGR on the HP 3000.
• protocol flags (code=144, length=4, 4-byte buffer)
(input). This option contains 32 bits of
protocol-specific flags. The following flags are
currently defined:
— no address (bit 17, input). (X.25 only.) This flag
provides the user with access to the entire X.25
call user data field (16 bytes or 128 bytes with
fast select). This option can be useful for
communication with non-HP nodes.
• facility field (code=145, length=n, n bytes) (input).
This option field defines the part of the facility field
built using the facility set. This data must follow the
X.25 recommendation and is appended to the
facilities from the facility set without any change.
See the discussion entitled “Facility Field” in
Chapter 1 , “NetIPC Fundamentals,” for more
information.
vcdesc (output)
32-bit integer, by reference. The returned VC socket
descriptor, a number identifying a VC socket belonging
to this process through which data can be sent or
received. This descriptor can be used in other intrinsics.
result (output)
32-bit integer, by reference. The error code
returned; zero if no error.
