Phase 2 with suspension of data reception for erasure of the flash memory
If the receiving BHT requires the flash memory to be erased for receiving downloaded
files, it sends a sequence of WACK and IDs to the sending station to suspend the
data transmission.
Upon receipt of the sequence of WACK and IDs, the sending station stops the data
transmission until any response comes from the receiving station for one minute.
If no response comes within one minute, the sending station sends a sequence of
DLE EOT and IDs and then aborts the current transmission.
