Static Passthrough Figure D-5 shows a terminal establishing a static passthrough session with the host,
logging on to and logging off from two host applications (TSO and CICS) and then
terminating the static passthrough session. Note that in the last sequence, LUNS
discards the USS message from the host and does not send it to $SSCP.
To establish the static path, LUNS uses an ESS table order record in which:
1. The character-coded command name is HOST
2. The STATIC parameter is specified ON
Another order record, whose character-coded command is TANDEM and whose
STATIC parameter is specified OFF, serves to take down the static path.
