A default registry entry always exists for a Hayes-compatible modem that is connected to COM1. You can specify additional external modems under the HKEY_LOCAL_MACHINE\ExtModemskey. Most of the values that are set for PCMCIA modems also apply to external modems, except that the following values are ignored for external modems.
| Value : type | Default | Description |

Unimodem.dll |
This value is redundant because Unimodem processes the ExtModemkeys. |

The following code example of registry entries will cause TAPI 2.0 to create a line device for the external modem from CompanyX and present it as one of the available TAPI devices. In this minimal example, all of the default settings from the HKEY_LOCAL_MACHINE\Driver\Unimodem\Initand \Settingskeys will be used.
