We manage to find them, but they are rare. Dell has some business
notebooks with them, and the Panasonic Toughbooks we have, have serial
ports. You can also find pc-cards that have serial outputs. However,
notebooks and desktops/towers are not used very often. Most of this
equipment talks to other pieces of stuff over serial connections
without a 'conventional computer' in the mix. Notebooks are used
mainly for service and troubleshooting.
