This object controls the maximum consequetive unacknowledged
frames, (1.....127) which an SDLC link station shall send without
an acknowledgement. This shall range from one to modulus minus one.
The modulus is controlled by the object: wfSdlcLSAdminMODULO. A
write operation to this administered value will not change the
operational value, wfSdlcLSOperMAXOUT, until the link station is
cycled inactive.
