changes the appropriate channel's Assembly 125 entry from 0xC0 Cyclic EDT
Get to 0x80 EDT Get or 0x40 Cyclic EDT Set to 0x00 EDT Set.
Whenever the adapter receives a ForwardOpen to an EDT module, the
adapter automatically rereads the module's Assembly 125 to gain a new view of
the assemblies. This reread is to check for any changes of CEDT Assemby
status to EDT status. If a CMD3 Disable Chx is received on any particular
channel, now the previous CEDT assembly is marked as an EDT assembly
and the adapter does not add that assembly to the CEDT scan. This
ForwardOpen reread happens any time a module receives a ForwardOpen,
including a Null-ForwardOpen received during system runtime.
