Serial Interface to PIC

This chapter discusses case studies developed for interfacing PIC through HyperTerminal. Following applications are developed:

• 1. 4.Configuring HyperTerminal

• 2. 4.2 Setting up HyperTerminal

• 3. 4.3 Displaying Data on HyperTerminal

• 4. 4.4 HyperTerminal Interface: Getting Sensor Signal on HyperTerminal

• 5. 4.5 HyperTerminal Based Control: Controlling an Actuator Such as Relay from PC HyperTerminal

• 6. 4.6 Controlling a Stepper Motor from HyperTerminal: HyperTerminal Keyboard Provides Direction

HyperTerminal is a data communications utility program that has been distributed with many Microsoft Windows^® operating systems, including Windows 95, Windows 98, Windows Me, Windows 2000, and Windows XP. It is a program for connecting a computer to other computers. It can also be set for accessing Telnet sites, bulletin board systems (BBSs), online services, using the connectivity options such as a modem or a null modem cable or even through Ethernet connection. With the advent of world wide web where sophisticated protocols are taking care of the online communication, the use of HyperTerminal has become almost rare. However for an embedded engineer, it is still a great debugging tool for testing the modems or send the commands to the embedded appliance connected to PC. It can be as well used for sending bulky files without setting up the network for the PC. Moreover, this is really useful for the old PCs where the setting up of the network is difficult.
