An asynchronous port on the computer used to connect a serial device to the computer and capable of transmitting one bit at a time. Serial ports are usually identified on IBM compatible computers as COM (communications) ports. For example, a mouse might connect to COM1 and a modem to COM2. The picture shows the DB9 serial connector on a cable.
Pots used by Fender. The middle one is a CTS pot (Chicago Telephone Supply, manufacturer #137) from the 30th week of 1966. The pots on the left and right are Stackpole pots (manufacture #304). Note the different position of the markings, even on pots from the same maker. Left: The source-date code (285709) on a speaker. In this case, the. 137733X is a 1973 pot. 137=CTS (manufacturer) 73=year, 3X=week of the year (last digit obscured). I'm not sure where that serial number might fall, but things get a little loose in the mid seventies. 1973-ish is probably about right for this. 250K pots are typically used with Fender Stratocaster's and Tele's, or other types of guitars using single coil pickups. Through pick guard mount will use a CTS short shaft pot (with a 1/4' bushing height), Bourns or CTS short shaft (3/8' bushing) should be used with a through body mount. Almost all of our CTS pots are either 450G or TAOT CUSTOMS.

Identifying a serial port
In the above graphic of a serial port, you can notice the DB9 serial port connection is easy to identify. The connection is in the shape of the letter D, is a male connector, and has 9 pins.
What is the serial port used for?
Below is a listing of various hardware components that can be purchased and used with your serial port.
Mouse - One of the most commonly used devices for serial ports, usually used with computers with no PS/2 or USB ports and specialty mice.
Modem - Another commonly used device for serial ports. Used commonly with older computers, however, is also commonly used for its ease of use.
Network - One of the original uses of the serial port, which allowed two computers to connect together and allow large files to be transferred between the two.
Printer - Today, this not a commonly used device for serial ports. However, was frequently used with older printers and plotters.
Serial port pin information
Below is a listing of each of the pins on the DB9 connector, their purpose, and signal name.
NoteWith many computers, the serial port is labeled as '10101' which are ones and zeros to represent binary. A user may also interpret the number '1' as the letter 'I' and the zeros as the letter 'O' and call it the 'IOIOI' port.
As shown above, pin one is in the top-left portion of the port and pin 9 is in the bottom right.
