TCP/IP STACK OPERATION

The eZ80 is made Internet-ready through its TCP/IP stack. The TCP/IP protocols shown in Table 3 are implemented through IPWorks networking code written by Metro Link. All of the protocols needed to operate an HTTP server are available and require only 50 KB of code to implement. Both UDP and TCP socket applications are supported.

Protocol	Description
Telnet	Telnet
HTTP	Hyper text transfer protocol
DHCP	Dynamic host configuration protocol
BOOTP	Bootstrap protocol
DNS	Domain name server
TCP	Transmission control protocol
UDP	User datagram protocol
IGMP	Internet group management protocol
ICMP	Internet control message protocol
IP	Internet protocol
ARP	Address resolution protocol
RARP	Reverse address resolution protocol
PPP	Point to point protocol
Table 3ıTCP/IP protocols available on the eZ80 Evaluation Board can be seen here. Future protocols supported include SMTP, FTP, TFTP, and SNMP.
