Chapter 17 Serial Communications
17.1 Synopsis
UNIX® has always had support for serial communications. In fact, the very first UNIX machines relied on serial lines for user input and output. Things have changed a lot from the days when the average terminal consisted of a 10-character-per-second serial printer and a keyboard. This chapter will cover some of the ways in which DragonFly uses serial communications.
After reading this chapter, you will know:
How to connect terminals to your DragonFly system.
How to use a modem to dial out to remote hosts.
How to allow remote users to login to your system with a modem.
How to boot your system from a serial console.
Before reading this chapter, you should:
Know how to configure and install a new kernel ([kernelconfig.html Chapter 9]).
Understand UNIX permissions and processes ([basics.html Chapter 3]).
Have access to the technical manual for the serial hardware (modem or multi-port card) that you would like to use with DragonFly.
