I have a need to control the dialer, modem, and phone hardware in the
AT&T pc7300 directly via ioctl calls in 'C'.  I have discovered two include 
files which seem to get me started in the right direction, but as is usually
the case, the information is "almost" complete. 

The /usr/include/sys/phone.h file seems complete with two useful structures, 
detailed descriptions of their members, and a list of ioctl commands used with 
them.

The /usr/include/sys/ph.h file contains five structures which include phone
line control, call progress detection, message waiting detection, modem 
control, and dial network control. To my disappointment however, the ioctl
commands necessary to use them are missing.  

Does anyone have additional information on this subject?

					thanks,
