This is regarding SDLC Point-to-Point Full Duplex.  Question is,
if the primary sends a Poll (eg: RR-P) followed by
couple of I-frames, should the secondary stick with the original
Nr (at the time the poll was received), or should it keep updating
the Nr;  correspondingly, should the primary do the same?

If this were to be true, then isn't it possible, that within one
POLL/FINAL exchange, any number of I-frames can be exchanged
between the Primary and the Secondary.

Could someone give an explanation; or point to some document with
these details.  The IBM SDLC document, simply has one scenario
regarding the Point-to-Point Full Duplex operation, without any
detailed discussion.

Thanks in advance.

Cheers,
divya
