7.7.18.6 Serial I/O Application Testing
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, but can be purchased separately from
http://www.hilgraeve.com. 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.
