The factory setting is 0.
H6: Buffer nearly-full threshold
This is a percentage from 0 to 99. The factory setting is 90.
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 sub-
ject 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.
Since DTR/DSR protocol is not used with the RS-422A standard, select a pa-
rameter value other than 0, 1, or 2 for the H5 setting when using the RS-422A
interface.
