���������� ITU-TSS V.35 interfaceBasically, V.35 is a high-speed serial interface designed to support both higher data rates and connectivity between DTEs or DCEs over digital lines.
���������� PC serial port (RS-232 DE9)This RS232C DE-9 (usually miscalled DB-9) port is very common and available at almost any PC, some Sun (at least Ultra 5/ 10, Blade 100/150) and many other computers. Document includes description of how PC serial mouse works.
���������� RS-232 (EIA-232) serial interfaceRS-232 is the standard serial communications interface found on all types of equipment such as computers, modems, printers, Microcontrollers, eprom programmers, and a host of other devices. Identical to the CCITT V.24/V.28, X.20bis/X.21bis and ISO IS2110 standards. RS232 pinout may be varied.
���������� RS-422 (EIA-422) serial interfaceRS422 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.
���������� RS-449 (EIA-449) interfaceThe 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.
���������� RS-530 (EIA530) interfaceEIA-530, or RS-530, is a balanced serial interface standard that generally uses a 25 pin connector. The RS530 isn´t an actual interfaceis, but a generic connector specification. The connector pinning can be used to support RS422, RS423, V.35 and X.21 to name the most popular ones.
���������� Apple GeoPortThe back panel of all Power Macintosh models contain two I/O ports for serial telecommunication data.
���������� Apple Macintosh RS-422It´s possible to connect RS-232 peripheral to the RS-422 port available on Macintosh computers. Use RXD- as RXD, TXD- as TXD, Ground RXD+, Leave TXD+ unconnected, GPi as CD.
���������� DEC Dual RS-232Found on the DEC Multia and DEC UDB (Universal Desktop Box). It contains two Serial ports on one connector. The 1st port is located on the normal pins, and the 2nd port is located on some "spare" pins.
���������� DEC MMJMMJ=Modified Modular Jack. Invented by Digital Equipment Corporation (DEC) (now: Compaq)
SGI
���������� SGI serial portThis connector can be found on Challenge, Onyx, Personal IRIS, and Power Series systems
���������� Serial (SGI MiniDIN)Mini-DIN-8 serial port connectors are found on the Personal IRIS 4D/30, 4D/35, Indigo, Indy, and Indigo2. Most of other SGI workstation uses standard PC serial pinout.
���������� C64 RS232 User portAvailable on the Commodore C64/C128. Software emulated. The signals does not have true RS232 levels. It´s TTL level, and RXD/TXD is inverted. It´s just the normal User port, used as a RS232 port.
