Initialization (LT side)
Acknowledgment (NT and LT side)
Corrupt CRCs (CCRC)
If the EOC Transparent mode is used on the NT side, or if one of the LT modes is used
(see "EOC Auto/Transparent Mode", page 55) this command requests the IEC-Q to
transmit corrupted (i.e. inverted) CRCs. It will be executed immediately.
If the EOC Auto mode is used on the NT side the IEC-Q will not react to this command.
This command is delivered by the MON-8 message (see also "MON-8 Codes", page
228).
Initialization (NT [transparent only], LT [auto/transparent])
No acknowledgment will be issued.
Normal (NORM)
Disables all previously sent MON-8 latching commands. The command may be used in
Auto and Transparent mode in LT modes and in Transparent mode in NT modes.
If the EOC Auto mode is used on the NT side the IEC-Q will not react to this command.
Initialization (NT [Transparent only], LT [Auto/Transparent]):
No acknowledgment will be issued.
