       termcap - terminal capability database

       The  termcap database is an obsolete facility for describ-
       ing  the  capabilities  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  termi-
       nal.   Programs  can  read  termcap to find the particular
       escape codes needed to control the  visual  attributes  of
       the  terminal actually in use.  (Other aspects of the ter-
       minal are handled  by  stty.)   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  sepa-
       rated 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 ver-
       sions 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

       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 exam-
       ple.  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 at last string capa-
       bilities,  each  sorted  alphabetically without looking at
       lower or upper spelling.  Capabilities  of  similar  func-
       tions 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 capabilities:

       Normal Characters except '^','\' and  '%'  repesent  them-

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

       \x  means  a  special code.  x can be one of the following
              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 char-
              acter xxx.

       i      Increments paramters by one.

       r      Single parameter capability

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

       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  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 document Minix termcap which may not be
              compatible with Linux termcap.

       The  block  grafic  characters  can  be specified by three
       string capabilities:

       as     start the alternative charset

       ae     end it

       ac     pairs of characters.  The first  character  is  the
              name  of  the  block  grafic  symbol and the second
              characters is its definition.

       The following names are available:

       +    right arrow (>)
       ,    left arrow (<)
       .    down arrow (v)
       0    full square (#)
       I    latern (#)
       -    upper arrow (^)
       '    rhombus (+)
       a    chess board (:)
       f    degree (')
       g    plus-minus (#)
       h    square (#)
       j    right bottom corner (+)
       k    right upper corner (+)
       l    left upper corner (+)
       m    left bottom corner (+)
       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.
