53541 2002-06-10 01:56:00 They are your serial data ports (used for external modems, serial mouse etc)- largely superfluous now that USB has taken over. Guest (0)
53542 2002-06-10 02:10:00 ....and/or to drive other external devices requiring a serial communication such as pen-plotters, digitisers, or control of electronic equipment. Guest (0)
53543 2002-06-10 04:03:00 How do you run a serial mouse from a com port?
About the only thing the average user will use them for is a modem.

53544 2002-06-10 06:02:00 Very useful for connecting to mainframes at 4800 baud --- using Kermit.

Being more up to date, you can make a programmer for the PIC microcontrollers which hangs on a serial port of a PC.
