Sorry maybe this is beginner question… I can login to TCP server with wizfi220 (PC hyperterminal), everything good, can use DHCP and WP2-PSK keyword security… but there is simple question… PC provide RTS and CTS, but my AVR uC can’t provide RTS and CTS… i tried to connect only RXD and TXD, but fail to write AT command…
Please give me explanation how to handle RTS and CTS on AVR/uC…
Regards,
