H4: Parity
The factory setting is 0 (none).
H5: Protocol logic
The factory setting is 0.
H6: Buffer nearly-full threshold
A percentage value from 0 to 99. The factory setting is 90.
H7: Buffer nearly-empty threshold
A percentage value from 0 to 99. The factory setting is 70. The factory
settings of the buffer nearly-full and nearly-empty thresholds (H6 and H7)
are subject to change without notice.
The difference between the nearly-full and nearly-empty thresholds allows
the computer to send a fairly large amount of data in a continuous stream.
H8: Received data buffer size
The input buffer size is specified in increments which vary depending on
the S5 parameter. When S5 is 0, the increment is 10KB. When S5 is 1, the
increment is 100KB. When S5 is 2, the increment is 1024KB. The factory
setting is 12 (1200KB, S5=1).
