Typedefs
typedef unsigned char	modem_speed_t
	Modem speed/protocol value type.

Detailed Description

Constants used in the modem driver.

This file contains constants that are used for the modem driver. You should not ever need to include this file directly, as the main modem driver header file includes it automatically.

Generally, you will not need to use the stuff in this file yourself at all, as the main modem header file defines many useful combinations for you.
