Chapter 21: Network Code Patterns in Tcl

---

Introduction

In this chapter, we look at simple socket-based applications in Tcl. These applications can serve as implemented software patterns for the construction of more advanced networking applications.

Note 

All software discussed here is also provided on the companion CD-ROM. Table 21.1 lists the applications and their locations on the CD-ROM.
