Chapter 8 deals with network connections: mailslots,
named pipes, UDP, and TCP. Each of the subdirectories
contains two halves of a communicating pair of 
programs: a sender and receiver that can communicate
over the network using a different protocol.

mcip - UDP packets
msip - TCP packets in a client/server relationsip (multiple 
       connections to the server)
msnp - Named pipe packets in a client/server relationship 
       (multiple indep. clients can connect to the server)
mtnp - Named pipe packets in a client/server relationship 
       (multiple indep. clients can connect to the server and 
       intercommunicate)
ranmon - Mailslots used to implement the "Run And Notify MONitor" 
       system
sms - Simple mailslot example
ssip - Simple point-to-point TCP connections
ssnp - Simple point-to-point named pipe connections

YOU MUST LOAD THE TCP/IP PACKAGE IN THE NETWORK APPLET OF THE
CONTROL PANEL BEFORE ANY TCP/IP CODE WILL WORK. SEE THE BOOK

Heterogeneous Networks" FOR INSTRUCTIONS.
