H7: Buffer nearly-empty threshold
This is a percentage 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 notification.
The gap 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
This is the size of the input buffer, specified in units of 10K bytes. The factory-set value is 6 meaning
60K bytes.
PRESCRIBE 2e FRPO D0 command
