You have to learn how to communicate with an RS-232 serial port from Ada, and then you have to read the manual for your modem concerning the AT command set that it implements (there are also some TIA/EIA and ITU-T recommendations on this subject, but better stick with your modem manual). How to access the serial port depends on your operating system. Under Linux for instance, just open the file /dev/cua1 and use the ioctl() C function (via pragma Import or via a POSIX.5 library such as florist). Markus -- Markus G.
