is the maximum packet size that will be transmitted on the port. Any frame exceeding
this size will be broken into segments, and the M-bit (more-bit) will be set to indicate
that more of the frame is coming.
determines which set of values will change, as described under "Database and System
Memory Values" on page 5-4.
prevents (if enabled) the HPAD from sending a Disconnect Request to the host if the
HPAD–TPAD connection is broken.
specifies the version (if any) of Link Problem Determination Aid that can be used by
a host program (e.g., NetView or VTAM) or controller program (e.g., NCP) to test
status and to control the line and remote interface. Configurable values are:
(Version 1), and (Version 2).

before it will declare the attached device down.

When the DTE is ready to transmit, it asserts RTS, waits for CTS to become
high, then starts transmitting. When transmission is finished, the DTE drops
RTS (and the DCE should drop CTS). DCD is low during this period.
When the DCE is ready to transmit, it checks to see that RTS and CTS are not
high, then it raises DCD and starts transmitting. When transmission is done, the
DCE drops DCD. RTS and CTS are low during this period.
For both Full and Half L1-Duplex, the DTE raises DTR and the DCE raises
DSR. The link is considered up when both DTR and DSR are high.
Make sure this parameter is configured correectly, or the PU will
not become active.
