GENERATING BREAK
The special reply string of BREAK will cause a break condition to
be sent. The break is a special signal on the transmitter. The
normal processing on the receiver is to change the transmission
rate. It may be used to cycle through the available transmission
rates on the remote until you are able to receive a valid login
prompt. The break sequence may be embedded into the send string
using the \K sequence.
