Modem Registry Keys

The following section describes data stored in specific modem registry keys that help advanced users correct problems with the commands Windows CE uses to control a modem.

Modem registry keys are stored under the following key.

HKEY_LOCAL_MACHINE\Drivers\PCMCIA\CompanyX-GenericModem-1234\

Each installed modem uses one registry key; additional subkeys, which contain AT commands that Windows CE uses to initialize and dial the modem, plus other entries that communication and modem drivers use.

Some of the more important entries you can use to correct or optimize modem operation are described in the following sections. The full set of modem registry keys are documented in the Windows CE Device Driver Development Kit.
