HyperTerminal can be used to set up a dial-up connection to another computer through the internal modem using Telnet or to access a bulletin board service (BBS) in another computer. It can also be used to set up a connection for data transfer between two computers (such as your desktop computer and a portable computer) using the serial ports and for serial-port control of external devices or systems such as scientific instruments, robots, or radio communications stations. HyperTerminal can also be used as a troubleshooting tool when setting up and using a modem. You can send commands through HyperTerminal to make sure that your modem is connected properly.
