A number of printers were released for the Commodore 64, both by Commodore themselves and by third-party manufacturers. Commodore-specific printers were attached to the C64 via the serial port and were capable of being daisy chained to the system with other serial port devices such as floppy drives.
Since the control signals for a serial port can be driven by any digital signal, some applications used the control lines of a serial port to monitor external devices, without exchanging serial data. A common commercial application of this principle was for some models of uninterruptible power supply which used the control lines to signal loss ...
It is frequently used to implement the serial port for IBM PC compatible personal computers, where it is often connected to an RS-232 interface for modems, serial mice, printers, and similar peripherals. It was the first serial chip used in the IBM PS/2 line, which were introduced in 1987. [2] [3] [4] The part was originally made by National ...
A serial port complying with the RS-232 standard was once a standard feature of many types of computers. Personal computers used them for connections not only to modems, but also to printers, computer mice, data storage, uninterruptible power supplies, and other peripheral devices.
A null modem adapter. Null modem is a communication method to directly connect two DTEs (computer, terminal, printer, etc.) using an RS-232 serial cable.The name stems from the historical use of RS-232 cables to connect two teleprinter devices or two modems in order to communicate with one another; null modem communication refers to using a crossed-over RS-232 cable to connect the teleprinters ...
Atari 8-bit computer peripherals include floppy drives, printers, modems, and video game controllers for Atari 8-bit computers, which includes the 400/800, XL, XE, and XEGS. [ 1 ] [ 2 ] [ 3 ] Because the Atari 400/800 8-bit computers were bundled with an RF modulator , stringent FCC regulations limiting radio emissions applied.

Two serial ports were provided primarily to support a printer and modem, and a floppy port connector supported a single external 5.25-inch drive (and later "intelligent" devices such as 3.5-inch drives and hard disks).
