How To Set Up Hyperterminal
ADDITIONAL INFORMATION. See the document on how to setup a Hyperterminal log. To monitor the boot sequence of MS systems, an RS232 cable with the COM1 port is used because this connection remains open even when TCP/IP (ethernet) connections are interrupted.
In order to set it up, first you have to find it on your computer. Long long ago, almost all computers had two serial ports, called 'COM1' and 'COM2', one a with a nine pin and the other with a 25 pin connector. Midi files for yamaha clavinova.
Now times have changed and the serial port has vanished.
Don't give up hope, however. The USB to serial converter has arrived, and it can be used instead. It is usually a dongle which plugs into a USB port, with a nine pin male connecter at the other end.
On my desktop computer, the motherboard has two built in serial ports. The third seial port, here labelled COM4, belongs to the USB to serial adapter I have plugged in.
So, to find the serial port on your computer, scout around its back. If you find a nine pin male connector (two rows, five and four, pins sticking out inside a metal shell) it has a serial port built in.
Or get a USB to serial converter and plug it in.

Starting HyperTerminal and setting up a new connection
Before you can use HyperTerminal to troubleshoot your modem, you must create a connection to the port the modem is using. To do so, follow these steps:
- Click Start Programs Accessories Communications HyperTerminal.
- Once HyperTerminal opens, it will automatically prompt you to create a new connection if none exist. If no connection(s) exists, you can click File New Connection to create a new one.
- Specify a name for the connection, choose an icon, and click OK.
- In the Connect To dialog box, choose the COM port being used by your modem (usually COM1 or COM2) from the Connect Using drop-down list and click OK.
- In the port property sheet that appears, choose a port speed (bits per second) that matches the device. (For a modem, choose its maximum speed.)
- Then, choose communications parameters that match the device. For most devices, you can typically use 8 data bits, no parity (set to None), one stop bit, and hardware flow control.
When you click OK, HyperTerminal will immediately open a connection to the port. You'll then be ready to troubleshoot.
Using AT commands
When using a modem, you can type AT and press [Enter] in the HyperTerminal connection to test communications. You should receive an OK message if your settings are correct and the modem is working, as shown in Figure A.

If you don't see the AT text appear when you type, choose File Properties, click the Settings tab, and then click ASCII Setup. Select Echo Type Characters Locally and click OK twice.
Once you know the modem is at least communicating with the computer, you can use an AT command to perform further diagnostic testing or change configuration settings. Refer to your modem's manual for configuration and diagnostic commands.
Other troubleshooting methods
There are a few other ways to perform diagnostics on a modem and issue special configuration commands. For diagnostics, open the Control Panel and then open the Phone And Modem Options object. Click the Modems tab, select the modem, and click Properties. Use the Diagnostics tab (Figure B) to query the modem and view the modem log when troubleshooting communications problems.

| Clicking the Query Modem button will send the same AT commands to the modem that we entered manually using HyperTerminal. |
If you need to include a special initialization command for the modem, click the Advanced tab and enter the modem commands in the Extra Initialization Commands field. This will cause Windows to use the initialization commands for all sessions in which the modem is used.
