This value must match the value set in the
other terminal. Note that this value must be
the same as the value programmed for the
packet size (G4 Parameter Switch 7, bits 0 to
3). Also, the transport block size is limited by
the amount of memory in the remote terminal.
Normally, do not change the default setting.
