host, and this communication protocol has variety of functionalities.
Receive mode for this communication protocol is multi buffer mode.
Receiving Buffer Control
This protocol has 2 contributing factors to detect receive buffer near full to control information like
receiving, print, cancel per item.
-
Contributing factor to receive buffer near full
◦ "Receive buffer near full" occurs when the buffer's free space goes down to 0.95 MB out of
the 2.95 MB of receive buffer.
◦ "Receive buffer near full" occurs when the buffer's free space goes down to 50 items out of
500 items of the history buffer.
-
Contributing factor to cancellation of receive buffer near full
◦ "Receive buffer near full" is cleared when the buffer's free space increased to 1.95 MB.
◦ "Receive buffer near full" is cleared when the buffer's free space increased to 200 items of
the history buffer.
