This document is for the UART serial port. This port has mostly
disappeared from desktops and laptops is still used elsewhere such as
for embedded systems. It covers information other than that which
should be covered by Modem-HOWTO, PPP-HOWTO, Serial-Programming-HOWTO,
or Text-Terminal-HOWTO. It lists info on multiport serial cards. It
contains technical info about the serial port itself in more detail
than found in the above HOWTOs and should be best for troubleshooting
when the problem is the serial port itself. If you are dealing with a
Modem, PPP (used for Internet access on a phone line), or a
Text-Terminal, those HOWTOs should be consulted first.
