An Introduction to TCP/IP Programming

This course describes the socket library functions and data structures for developing TCP/IP applications. Practical examples are presented and students will write their own TCP/IP sockets-based applications. Troubleshooting and debugging techniques are also presented.

A variation of this course specific to the OpenVMS environment, including TGV/Cisco/Process Software's MultiNet, UCX routines, and the OpenVMS $QIO calling standard is also available.
