Callback package for Linux
Version:
1.21
Description:
This package allows callback for Linux systems which are
equipped with a modem. Prerequisites are: setserial 2.0.2 or
higher and getty_ps 2.0.7b or higher. Contained are three
programs: cblogin, a login-program for dial-in connections,
cbgetty, a pseudo-getty and cbstat, a user-administrator's
tool. The package contains a file callback.doc, which provides a
comprehensive guide to the installation of a dial-in and
dial-out modem before addressing the callback issue. This guide
may be valuable even for the `bare' modem installation.
