• DEC MMJ connector MMJ=Modified Modular Jack. Invented by Digital Equipment Corporation (DEC) (now: Compaq)
• EIA-449 (RS-449) Secondary connector Common names: EIA-449, RS-449, ISO 4902. Secondary (auxilary) channel
• EIA-449 (RS-449) interface The RS449 interface is a generic connector specification. It´s not an actual interface. The connector pinning was originally designed to support RS422 for balanced signals, and RS423 for the unbalanced signals. And should have been the succesor of RS232.
• EIA530 (RS530) interface The RS530 interface is a generic connector specification. It´s not an actual interface. The connector pinning can be used to support RS422, RS423, V.35 and X.21 to name the most popular ones.
• ITU-TSS V.35 connector Basically, V.35 is a high-speed serial interface designed to support both higher data rates and connectivity between DTEs or DCEs over digital lines.
• ITU-TSS X.21 connector Common names: ITU-TSS (CCITT) X.21, ISO 4903
• RS-232D connector 
• RS232 interface RS232 is a serial interface. It can be found in many different applications where the most common ones are modems and Personal Computers.
• RS366 interface 
• RS422 9pin connector 
• RS422 interface RS422 is a balanced serial interface for the transmission of digital data. The advantage of a balanced signal is the greater immunity to noise. The EIA describes RS422 as a DTE to DCE interface for point-to-point connections.
• RocketPort Serialport connector Available at RocketPort serialport expansion cards.
• Serial (15) connector Seems to be available at a 14.4kbps modem called Speedster.
• Serial (DB25) connector Very common PC serial port.
• Serial (PC 9) connector This port is very common and available at almost any PC, some Sun (at least Ultra 5/ 10, Blade 100/150) and many other computers. With description of how PC serial mouse works.
• Serial (Printer) connector 

• Apple 300/1200 Modem connector
