Radio observations of nine pre-main-sequence stars at 15 or 23 GHz are presented to show that the radio spectrum not only allows the derivation of ionized envelope properties and the mass flow rate, but can also be useful in understanding the stars' ultraviolet, optical and near-infrared continua. Emphasis is on T Tauri and DG Tauri, and it is suggested that T Tauri's stellar wind most likely originates in a very hot region where electron temperatures in the envelope are not less than about 1 million K, with the wind itself the continuation toward high temperatures of the 100,000 K region observed at IUE ultraviolet wavelengths. This suggestion is supported by the conclusion that the acceleration region of the wind, if it does exist, must be very small.
