When my hard drive failed, it was replaced, under warranty, by a computer specialist. It was my responsibility to reload the software. Using the restore software from the computer manufacturer, I supposedly returned the software to its original configuration.
Most programs seem to work fine.
However, when I went to set up a new profile in HyperTerminal, I discovered that the required country code box was blank. The country-code pulldown menu was blank and would not allow me to type in a country code. After a great deal of playing around, I finally located a way to bypass the area and country codes and set up a HyperTerminal profile for a local number. This problem can occur if one of the Windows 95 Telephony Application Programming Interface files or one of the files for the program you are using has been damaged. Delete the Telephon.ini file in the Windows folder.
