SYMPTOMS
After you disconnect and then reconnect a serial cable, programs may not be able to use a serial modem device to make a telephone connection if the device is configured to accept incoming connections.
Additionally, when you use HyperTerminal, you may experience a Telephony API (TAPI) error. You may also be prompted to restart HyperTerminal. This problem occurs even after you make sure that a modem is installed by using the Phone and Modem item in Control Panel.
This behavior may also occur after you turn the modem off and then turn the modem on.
