This object controls the maximum number of
unacknowledged I-frames which an SDLC link
station may receive. This should range from 1
to (sdlcLSAdminMODULO - 1). This value is sent
in the XID to the ALS.
A write operation to this administered value
will not change the operational value,
sdlcLSOperMAXIN, until the link station is
cycled inactive.
