mapchan(F)


mapchan -- format of device mapping files

Description

A mapchan file configures the mapping of information between the character sets used by devices and the internal character set used by the system.

Each unique channel map requires a multiple of 1024 bytes (a 1KB buffer) for mapping the input and output of characters. No buffers are required if no channels are mapped. If control sequences are specified, an additional 1KB buffer is required.

A method of sharing maps is implemented for channels that have the same map in place. Each additional, unique map allocates an additional buffer. The maximum number of map buffers available on a system is configured in the kernel, and is adjustable via the NEMAP kernel parameter (see ``Hardware and device driver parameters'' in the Performance Guide). Buffers of maps no longer in use are returned for use by other maps.

Example of a mapchan file

The internal character set is defined by the right column of the input map, and the first column of the output map in place on that line. The default internal character set is the 8-bit ISO 8859-1 character set, which is also known as dpANS X3.4.2 and ISO/TC97/SC2. It supports the Latin alphabet and can represent most European languages.

Any character value not given is assumed to be a straight mapping: only the differences are shown in the mapchan file. The left-hand columns must be unique. More than one occurrence of any entry is an error. Right-hand column characters can appear more than once. This is ``many to one'' mapping. Nulls can be produced with compose sequences or as part of an output string.

It is recommended that no mapping be enabled on the channel used to create or modify the mapping files. This prevents any confusion of the actual values being entered due to mapping. It is also recommended that numeric rather than character representations be used in most cases, as these are not likely to be subject to mapping. Use comments to identify the characters represented. Refer to the ascii(M) manual page and the hardware reference manual for the device being mapped for the values to assign.

   #
   # sharp/pound/cross-hatch is the comment character
   # however, a quoted # ('#') is 0x23, not a comment
   #
   # beep, input, output, dead, compose and
   # control are special keywords and should appear as shown.
   #
   beep       		# sound the bell when errors occur
   input
   

'a' 'b' 'c' 'd'

dead 'p' 'q' 'r' # p followed by q yields r 's' 't' # p followed by s yields t

dead 'u' 'v' 'w' # u followed by v yields w

compose 'x' # x is the compose key (only one allowed) 'y' 'z' 'A' # x followed by y and z yields A 'B' 'C' 'D' # x followed by B and C yields D

output 'e' 'f' # e is mapped to f 'g' 'h' 'i' 106 # g is mapped to h i j - one to many 'k' 0x6c 0155 'n' # k is mapped to l m n

control # the control sections must be last

input E 1 # the character E is followed by # 1 more unmapped character

output FG 2 # the characters F G are followed by # 2 more unmapped characters

All of the single letters above preceding the ``control'' section must be in one of these formats:

'j' # quoted character
106 # decimal value
0x6a # hexadecimal value
0152 # octal value

All of the above formats are translated to single byte values.

The control sections (which must be the last in the file) contain specifications of character sequences which should be passed through to or from the terminal device without going through the normal mapchan processing. These specifications consist of two parts: a fixed sequence of one or more defined characters indicating the start of a no-map sequence, followed by a number of characters of which the actual values are unspecified.

To illustrate this, consider a cursor-control sequence which should be passed directly to the terminal without being mapped. Such a sequence would typically begin with a fixed escape sequence instructing the terminal to interpret the following two characters as a cursor position; the values of the following two characters are variable, and depend on the cursor position requested. Such a control sequence would be specified as:

   \E=	2	# Cursor control: escape = <x> <y>
There are two subsections under control: the input section is used to filter data sent from the terminal to UNIX, and the output section is used to filter data sent from UNIX to the terminal. The two fields in each control sequence are separated by white space, that is the Space or Tab characters. Also the number sign (#) introduces a comment, causing the remainder of the line to be ignored. Therefore, if any of these three characters are required in the specification itself, they should be entered using one of alternative means of entering characters, as follows:

^x
The character produced by the terminal on pressing the <Ctrl> and x keys together.

\E or \e
The <Esc> character, octal 033.

\c
Where c is one of b, f, l, n, r or t, produces Backspace, Formfeed, Linefeed, Newline, Carriage Return, or Tab characters respectively.

\0
Since the NULL character can not be represented, this sequence is stored as the character with octal value 0200, which behaves as a NULL on most terminals.

\nn or \nnn
Specifies the octal value of the character directly.

\
followed by any other character is interpreted as that character. This can be used to enter Space, Tab, or Hash characters.

Using character mapping

Certain characters in the ISO 8859-1 character set are not assigned to specific keys since most terminals do not have enough keys to assign one to each character. Two methods of entering these characters are provided:

Dead key sequences

A dead key generates no output when pressed, but displays a character when a subsequent key is pressed. Such a key can give you an accented character which is not present on the keyboard as a specific key. The character is a combination of a dead key (the accent character) and the following key. For example, pressing the ``´'' dead key followed by an ``a'' displays the accented character á.

To display the dead key character, press it twice.

Six dead keys are supported by the supplied mapchan files. See ``Supported dead keys'' for details.

The following tables show which characters can be produced using the dead keys. There are six tables, each corresponding to a dead key. The second key is the key to press after pressing the dead key; the value is the hexadecimal value of the resulting character.

Supported dead keys

Six dead keys are supported by the mapchan files provided with the SCO OpenServer(TM) system. The mapchan files for the following terminals use the specified dead keys. The other mapchan files do not provide dead keys, but can be modified to do so:

See the mapchan(M) manual page for a table of mapchan files and keyboards.

Compose sequences

Compose sequences allow you to press a number of keys to generate a particular character. The sequence starts with the compose key and is completed by two further keys, which specify the character input.

For example, the registered trademark symbol (®) can be generated by pressing the following:

<compose key> r o

Some keyboards have a compose key marked as such. To use this compose key you should refer to the manual for the terminal.

All supplied mapping files use <Ctrl>_ (control underscore) as the character to introduce a compose sequence. The PC console keyboard maps also use the <SysReq> key to introduce compose sequences; on keyboards with 12 function keys, the alternate compose key is the ``*'' on the number pad.

The supplied compose sequences have alternatives. This is because some sequences are needed to cover the cases where characters are not present on the keyboard and so cannot be used as part of a compose key sequence.

The following characters have not been used as elements of the minimal compose sequence, since they are not present on certain keyboards:

# $ @ [ \ ] ^ ` { | } ~

The following table shows all the characters available with the various compose sequences:
