Windows 7 does not have the HyperTerminal communications and terminal emulation program built into the operating system. Installing the Windows XP HyperTerminal client on Windows 7 is possible. Also, a version of HyperTerminal is available on the Internet for download for personal use.
Access a Windows XP machine, and copy the hypertrm.dll and hypertrm.exe files in the ZIP format to the Windows 7 system. Extract the two files, and save them into the same folder. Launch the HyperTerminal client by clicking twice on the hypertrm.exe file, and it is ready for use.
The Windows remote shell function and Telnet can help in serving specific functions of HyperTerminal. To obtain remote shell access only, replace the HyperTerminal function with the Windows Remote Shell function. Enter the Windows remote shell command followed by a backslash at the command prompt, and then press the Enter key. To set up a dial-up connection to another computer through the internal modem, use Telnet.
To troubleshoot the modem problems, replace the HyperTerminal function, using the phone and modem option. First, click on the Start button, and then select the Control Panel. Enter "phone and modem" in the search box option field, and then click on Phone and Modem. Prior to accessing the Phone and Modem dialog box, provide the country or region details in addition to the special phone-dialling rules.
To control serial devices, use the downloadable version of HyperTerminal that is available on the Internet.
