1)
MicroSmart A transmits data with the TXD command, and becomes ready to receive data with the RXD
command. Web Server Unit A transmits the data sent from MicroSmart A to Web Server Unit B (to which the
target IP address, the service and the target port number are registered).
2)
Web Server Unit B receives the data addressed to it, and transmits data to MicroSmart B. MicroSmart B
receives the data with the RXD command.
3)
MicroSmart B transmits data with the TXD command. Web Server Unit B transmits the data sent from
MicroSmart B to Web Server Unit A.
4)
Web Server Unit A receives the data addressed to it and transmits data to MicroSmart A. MicroSmart A receives
