This value is sent in the CR packet. This value
must match the value stored in the other terminal,
or communication will stop (CI will be returned). If
the other end returns CI, check the value of the
packet window size with the other party.
Note that this value must be the same as the
value programmed for the transport block size
(G4 Parameter Switch B, bits 0 to 3).
Normally, do not change the default setting.

This is the maximum number of unacknowledged
packets that the machine can send out before
having to pause and wait for an
acknowledgement from the other end.
This should be kept at 7 normally.
If the packet modulus (G4 Parameter Switch 6, bit
4) is 8, the packet window size cannot be more
than 7. However, if the packet modulus is 128, the
window size can be up to 15. Also, if the layer 3
protocol setting (G4 Parameter Switch 6, bit 0) is
at IS8208, the packet window size cannot be
more than 7.
