6ft DB9 Null Modem Cable - Male to Female
Serial, not Cereal
We are not talking about your breakfast cereal today. No! We are talking about serial technology. Computers have used Serial communication for many years, though not as widely used in today’s market. When most people refer to serial, they think of the DB9 cable. It is referred to as DB9 because it carries 9 pins within it. DB9 was typically used for devices such as gamepads, mice, keyboards, or other such interface devices.
What we have here is a FireFold brand 6 foot DB9 male to female serial null-modem cable. Null modems are usually used to connect DTE (data terminal equipment) like terminals or printers using an RS-232 cable. Originally, the RS-232 standard was developed and used for teleprinter machines that could communicate over phone lines. This was so that you would not have to use an actual modem for transferring information between the two devices.
