    Internet. Similarly, the ezTCP series perform TCP/IP protocol processing on data received from the Internet and sends the processed data to the serial port. EZL-300W Lite(it is pronounced as “lait”), which is one of ezTCP products, provides TCP/IP communication through IEEE802.11b (wireless LAN). In other words, like other ezTCP products, EZL-300W Lite TCP/IP-processes data received from the serial port and sends the processed data to the wireless LAN network.
