b. The receiving unit (FI-30 Server) will Confirm message:
"$PSILBPS,19200,C,<CR><LF>"
and send it back on output ports to the requesting unit.
c. When the requesting unit receives the same message but with the flag set to "C"
(Confirmed), both server ports (A and B) are set to 19200bps and transmission may
start at the new baudrate. The sending unit may now stop sending the proprietary
request message since it has entered the higher baudrate. There is no way back
unless there is a power loss.
From power up, baudrate is always set to 4800 and the above procedure must be
repeated.
The receiving unit (FI-30 Server) will always check for the proprietary message when in
normal baudrate, not when in high baudrate.
