7.8.8.6 Testing Applications
7.8.8.6.1 Configure HyperTerminal
A common problem when developing a serial I/O application is the lack of an
immediately available serial device with which to develop and test programs.
Using HyperTerminal, a developer can simulate the output of a serial device or
capture serial input.
Note HyperTerminal is provided as a utility with Windows XP and earlier
versions of Windows. HyperTerminal is not provided with later versions of
Windows. HyperTerminal automatically converts binary data to ASCII on the
screen. Binary data can be captured, saved to a file, and then viewed with a
hexadecimal editor. Other terminal emulators are available from third-party
vendors that facilitate capture of binary or hexadecimal data.
Create a HyperTerminal instance file by clicking Start | All Programs |
Accessories | Communications | HyperTerminal. The windows in the figures
HyperTerminal Connection Description (p. 212) through HyperTerminal ASCII
Setup (p. 213) are presented. Enter an instance name and click OK.
