5.2 Sample Computer Link Protocol Program

This section shows a sample program that runs on the host computer (a personal
computer or workstation) and that uses computer link protocol transmission.

This program issues a read/write request for 32 words from the start of the S controller D
registers.

Operating environment

• Hardware: Toshiba J-3100PV, PC/AT compatible

3Com Etherlink III (3C509/B)

• Software: PC-NFS Pro 1.1.1.0

Microsoft + 1.0

Transfer parameters

• Local IP address:

133. 113. 98. 200

• Local UDP port number:

3001

• Remote IP address:

133. 113. 98. 10

• Remote UDP port number: 3001
