All USB hubs can operate at this rate. High speed (HS) rate of 480 Mbit/s was introduced in 2001 by USB 2.0. High-speed devices must also be capable of falling-back to full-speed as well, making high-speed devices backward compatible with USB 1.1 hosts. Connectors are identical for USB 2.0 and USB 1.x. SuperSpeed (SS) rate of 5.0 Gbit/s. The ...
The expansion to 1200 and 2400 baud required the addition of new commands, some of them prefixed with an ampersand (&) to denote those dedicated to new functionality. Hayes itself was forced to quickly introduce a 2400 baud model shortly after their 1200, and the command sets were identical as a time-saving method. [ 6 ]
The initial character TS encodes the convention used for encoding of the ATR, and further communications until the next reset. In direct [resp. inverse] convention, bits with logic value '1' are transferred as a High voltage (H) [resp. a Low voltage (L)]; bits with logic value '0' are transferred as L [resp. H]; and least-significant bit of each data byte is first (resp. last) in the physical ...
The speed (or baud rate) includes bits for framing (stop bits, parity, etc.), thus the effective data rate is lower than the baud rate. For 8-N-1 encoding, only 80% of the bits are available for data (for every eight bits of data, ten bits are sent over the serial link — one start bit, the eight data bits, and the one stop bit).

The baud unit is named after Émile Baudot, the inventor of the Baudot code for telegraphy, and is represented according to the rules for SI units.That is, the first letter of its symbol is uppercase (Bd), but when the unit is spelled out, it should be written in lowercase (baud) except when it begins a sentence or is capitalized for another reason, such as in title case.

The COM ports are interfaced by an integrated circuit such as 16550 UART.This IC has seven internal 8-bit registers which hold information and configuration data about which data is to be sent or was received, the baud rate, interrupt configuration and more.
