While a SECS-II connection is being established, the SDR component of the GEM interface
buffers all the messages to be sent to the host computer. If the SECS-II connection cannot be
established within the number of seconds specified for TG, these buffered messages will be
sent to the host computer. Otherwise they are rejected by the SDR component and have the
status F_DELV.

The SDR component of the GEM interface tolerates the status that all internal buffers are full
and that the host is attempting to send further data packets for up to the number of seconds
specified for MS. The TCP/IP connection is then ended to prevent the network becoming over-
loaded.
