10 Mbit/s: 1.25 MB/s: USB 1.0 full speed: 12 Mbit/s: 1.5 MB/s: 1996 Parallel (Centronics/IEEE 1284) EPP (Enhanced Parallel Port) 16 Mbit/s: 2 MB/s: 1992 Parallel (Centronics/IEEE 1284) ECP (Extended Capability Port) 20 Mbit/s: 2.5 MB/s: 1994 Serial EIA-485 max. If you use a USB-based serial adapter, there's no 16550 involved and the limit is instead set by the specific chip(s) used in the adapter, of course Serial EIA-422 max.

I believe the classical PC UART (the 16550) in modern implementations can handle at least 1.5 Mbps. (N)one is the default The maximum speed is limited by the specs of the UART hardware. cParity: Parity can be defined with one of these values: (E)ven, (O)dd, (M)ark, (S)pace, or (N)one. If no value is set, a default of 110 is used.

Thus such ports behave just like 115.2k ports unless the higher speeds are enabled by special software Defines the serial port baud rate or transmission speed. Unfortunately Linux seldom uses these speeds due to lack of drivers. But by the year 2000, most new serial ports supported higher speeds of 230.4k and 460.8k. Serial COM port pinouts for both DB-9 & DB. Now we will have a look at the pinouts of both DB-9 and DB-25 connectors: Figure 5. Serial port speeds (bits/second) and data transfer speeds.
The following table shows the speeds at which most computers' serial ports are able to run and how many KB/sec they translate to: Figure 4. The serial port of a computer is able to run at different speeds, thus allowing us to connect different devices which communicate at different speeds with the computer. Serial ports use two-level (binary) signaling, so the data rate in bits per second is equal to the symbol rate in baud [1 The configuration for serial ports designed to be connected to a PC has become a de facto standard, usually stated as 9600/8-N-1. The kernel supports a much wider range of serial bit rates when the serial interface is not being used as a serial console. The Linux kernel on a modern PC supports a serial console speeds of 1200, 2400, 4800, 9600, 19200, 38400, 57600 bits per second. For other speeds, the bits/second figure and the baud may or may not be the same: it depends upon the encoding used to carry the signal The speed of the serial link in bits per second. For asynchronous speeds at or below 600 bps and all synchronous speeds listed, this number is also the same as the baud (not baud rate). Note: these table list rates in bits per second.
