The HyperTerminal VT100J character set option supports the use of ASCII Double Byte Character Set (DBCS) characters in the transmitted data stream. DBCS provides support for extended language alphabets and for some East Asian language alphabets, including Chinese, Japanese, and Korean.
DBCS uses the numbers 0–128 to represent the US-ASCII character set. Some numbers greater than 128 function as lead-byte characters, which are indicators that the following value is a character from a non-Latin character set. In DBCS, ASCII characters are only 1 byte in length, whereas Japanese, Korean, and other East Asian characters are 2 bytes in length. For more information on DBCS, contact the ANSI standards organization.
For a HyperTerminal terminal emulation protocol, the supported keyboard characters visible on the wire are unchanged by the selection of the HyperTerminal VT100J character set option. Each supported keyboard key retains its original mapping, either to a single US-ASCII character or to an escape sequence of multiple US-ASCII characters.
For a HyperTerminal file transfer protocol, the supported packet control and data characters visible on the wire are unchanged by the selection of the HyperTerminal VT100J character set option. Each packet control character retains its original mapping, either to a single US-ASCII character or to an escape sequence of multiple US-ASCII characters. Each data character in the transferred file is transmitted as an 8-bit byte and so retains the original encoding of the file.
