5. Throughput enhancement. In between a command and its reply
the URFI will ignore the serial port, to reduce overhead and improve
throughput. If the URFI fails to respond in the maximum time for that
command the S/W can reset the URFI by toggling the serial port
DTR line.
6. URFI response. After all replies, the URFI will resend the “URF>”
cursor to acknowledge it is ready for another command. Except after
the Stand-By or Power-Down commands, because it will not be
ready then. Invalid command strings will return “INVALID” at the
point where the error is found, and the rest of the command line is
ignored.
7. Set-up. Setup parameters will all be saved in non-volatile memory
(EEPROM) so they can be set once, at the factory or with a PC. The
S/W will not be required to perform any special setup commands
each time the URFI is powered up. Use the “UE” command to save
the current setup to EEPROM as the new defaults.
