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 FreeBSD uses serial communications.
After reading this chapter, you will know:
How to connect terminals to your FreeBSD 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 (章 8, 設定 FreeBSD Kernel).
Understand UNIX® permissions and processes (章 3, UNIX 基礎概念).
Have access to the technical manual for the serial hardware (modem or multi-port card) that you would like to use with FreeBSD.
