Installing on a Linux Computer
These instructions describe how to install a modem on a computer using RedHat Linux 6.2 operating system.
Other versions of RedHat and other Linux operating systems should be similar. With Linux, you do not need
drivers for most standard external modems and most internal ISA bus modems. Programs in Linux commonly call
upon the port, rather than the modem.
