atdialer

The dialer binaries reside in /etc/uucp. These dialers (for example, Courier_V.34_Data_Fax_Modem) are implemented by mdmcfg(1M) as symbolic links to a single executable (/usr/lib/uucp/atdialer) together with an editable configuration file in /etc/uucp/default. In /etc/uucp/default/term/00m two files are generated that are named after the modem, one with a .cfg ending and one without. For example, Courier_V.34_Data_Fax_Modem and Courier_V.34_Data_Fax_Modem.cfg. The file without the .cfg is a traditional UnixWare dialer file that is generated from the .cfg file.
