atdialer and dialer programs

atdialer and dialer programs

There are two types of dialer binaries, named dial* and atdial*, in /usr/lib/uucp. The dial binaries (for example, dialHA24) are separate executable programs that must be recompiled from source files if you wish to customize them. The atdial dialers (for example, atdialHAY) are implemented as symbolic links to a single executable (/usr/lib/uucp/atdialer) together with an editable configuration file in /usr/lib/uucp/default.

Table 24-2 lists symbolic links to atdialer and dialer programs provided with SCO OpenServer systems. Both atdialer and the dialer programs are supplied in binary and source form.
