HP-UX SNAplus2 R7 NOF Programmer's Guide

NOF API Verbs
DEFINE_LS
no_resp_timer_retry
Number of times an adjacent secondary station is seen to fail to respond before the primary sends an outage
message to the DLC user.
A value of
0xFFFF indicates an unlimited retry count. A value of 0x0001 indicates that an outage should
be generated after the first timer expiry.
rem_busy_timer
Time allowed for an adjacent secondary station to be in an RNR condition. This is used in conjunction with
the retry limit value to provide the overall time before an outage message is sent. The timer is speci
fied in
milliseconds.
rem_busy_timer_retry
Used in conjunction with the timeout value to provide the overall timeout before an outage message is sent.
A value of 0xFFFF is used to indicate an unlimited retry count. A value of 0x0001 indicates that an outage
should be generated after the first timer expiry.
rr_timer
The time in milliseconds to wait before turning the poll bit around when the SDLC component has no work
to do.
This field may be set to zero, or to a nonzero value if the immediate turn-around causes hardware problems
on the link. Higher values can also be used to optimize link usage, because often the higher-level software
will generate data in response to the data contained in an I-frame carrying the poll bit; the pause allows the
data to be received and processed.
poll_frame
The frame to use for pre-activation polling. This is normally XID, indicating that polling is in the control of
the DLC user. However, when SNAplus2 is primary talking to an old secondary implementation, it may be
necessary to poll using some other frame. Possible values are: XID, DISC, SNRM, SNRME, TEST.
poll_on_iframe
Specifies whether this link station is permitted to send the poll bit on an I-frame. This allows SNAplus2 to
work with certain SDLC implementations which do not handle receipt of I-frames carrying the poll bit.
Possible values are:
AP_YES
This link station is allowed to send the poll bit on an I-frame.
AP_NO
This link station is not allowed to send the poll bit on an I-frame.
stub_spec_data_len
Length of the Stub specific data that follows. Set this to size of (STUB_SPEC_DATA).
stub_spec_data
Stub specific data. These fields are used only for switched outgoing links. The values specified in this
structure override those defined in the Stub specific data for the port that owns this LS; where fields in this
structure are shown as reserved, the values from the port are used instead. For switched incoming links or
leased links, the parameters defined in the Stub specific data for the port (not for the LS) are used.
The structure contains the following fields:
stub_spec_data.opt1
HMOD port options flag 1. Set the appropriate bits of this field as follows (bit 7 is the most significant bit):
bit 7
