A DB-25 connector as described in the RS-232 standard Data circuit-terminating equipment (DCE) and data terminal equipment (DTE) network. In telecommunications, RS-232 or Recommended Standard 232 [1] is a standard originally introduced in 1960 [2] for serial communication transmission of data.
A four-port serial (RS-232) PCI Express ×1 expansion card with an octopus cable that breaks the card's DC-37 connector into four standard DE-9 connectors A converter from USB to an RS-232 compatible serial port—more than a physical transition, it requires a driver in the host system software and a built-in processor to emulate the functions ...

Maximum standard speed of both of the 2692's channels is 115.2 kbit/s. The 26C92 is an upwardly compatible version of the 2692, with 8-byte transmitter and receiver FIFOs for improved performance during continuous bi-directional asynchronous transmission (CBAT) on both channels at the maximum standard speed of 230.4 kbit/s.
Serial cables are typically used for RS-232 communication. A serial cable or RS-232 cable is a cable used to transfer information between two devices using a serial communication protocol. The form of connectors depends on the particular serial port used. A cable wired for connecting two DTEs directly is known as a null modem cable.
Therefore, bus master memory cycles are the only allowed DMA in this standard. [30] eSPI subs are allowed to use the eSPI main as a proxy to perform flash operations on a standard SPI flash memory sub on behalf of the requesting eSPI sub. [30] 64-bit memory addressing is also added, but is only permitted when there is no equivalent 32-bit ...
RS-232 connector (D-Sub DB-25 variant) Many communication systems were generally designed to connect two integrated circuits on the same printed circuit board, connected by signal traces on that board (rather than external cables). Integrated circuits are more expensive when they have more pins. To reduce the number of pins in a package, many ...
