The  termcap  database is an obsolete facility for describing the capa-
       bilities of character-cell terminals and printers.  It is retained only
       for  capability  with old programs; new ones should use the terminfo(5)
       database and associated libraries.

       /etc/termcap is an ASCII file (the  database  master)  that  lists  the
       capabilities  of  many different types of terminals.  Programs can read
       termcap to find the particular escape codes needed to control the  vis-
       ual  attributes of the terminal actually in use.  (Other aspects of the
       terminal are handled by stty(1).)  The termcap database is  indexed  on
       the TERM environment variable.

       Termcap entries must be defined on a single logical line, with '\' used
       to suppress the newline.  Fields are separated by ':'.  The first field
       of  each  entry  starts at the left-hand margin, and contains a list of
       names for the terminal, separated by '|'.

       The first subfield may (in BSD termcap entries from  versions  4.3  and
       prior)  contain  a short name consisting of two characters.  This short
       name may consist of  capital  or  small  letters.   In  4.4BSD  termcap
       entries this field is omitted.

       The  second  subfield  (first, in the newer 4.4BSD format) contains the
       name used by the environment variable TERM.  It should  be  spelled  in
       lowercase  letters.   Selectable hardware capabilities should be marked
       by appending a hyphen and a suffix to this  name.   See  below  for  an
       example.   Usual  suffixes  are  w  (more  than 80 characters wide), am
       (automatic margins), nam (no automatic margins), and rv (reverse  video
       display).   The third subfield contains a long and descriptive name for
       this termcap entry.

       Subsequent fields contain  the  terminal  capabilities;  any  continued
       capability lines must be indented one tab from the left margin.

       Although  there  is  no  defined  order, it is suggested to write first
       boolean, then numeric, and then string capabilities, each sorted alpha-
       betically  without looking at lower or upper spelling.  Capabilities of
       similar functions can be written in one line.

       Example for:

       Head line: vt|vt101|DEC VT 101 terminal in 80 character mode:\
       Head line: Vt|vt101-w|DEC VT 101 terminal in (wide) 132 character mode:\
       Boolean: :bs:\
       Numeric: :co#80:\
       String: :sr=\E[H:\

       There are several ways of defining the control codes for  string  capa-

       Every normal character represents itself, except '^', '\', and '%'.

       A ^x means Control-x.  Control-A equals 1 decimal.

       \x means a special code.  x can be one of the following characters:
              E Escape (27)
              n Linefeed (10)
              r Carriage return (13)
              t Tabulation (9)
              b Backspace (8)
              f Form feed (12)
              0 Null character.  A \xxx specifies the octal character xxx.

       i      Increments parameters by one.

       r      Single parameter capability

       +      Add value of next character to this parameter and do binary out-

       2      Do ASCII output of this parameter with a field with of 2

       d      Do ASCII output of this parameter with a field with of 3

       %      Print a '%'

       If you use binary output, then you  should  avoid  the  null  character
       ('\0')  because  it  terminates the string.  You should reset tabulator
       expansion if a tabulator can be the binary output of a parameter.

              The above metacharacters for parameters may be wrong, they docu-

       The block graphic characters can be specified by three string capabili-

       as     start the alternative charset

       ae     end it

       ac     pairs  of  characters.   The  first character is the name of the
              block graphic symbol and the second characters  is  its  defini-

       The following names are available:

       +    right arrow (>)
       ,    left arrow (<)
       .    down arrow (v)
       n    cross (+)
       o    upper horizontal line (-)
       q    middle horizontal line (-)
       s    bottom horizontal line (_)
       t    left tee (+)
       u    right tee (+)
       v    bottom tee (+)
       w    normal tee (+)
       x    vertical line (|)
       ~    paragraph (???)

       The  values  in  parentheses  are  suggested defaults which are used by
       curses, if the capabilities are missing.
