NAME
     termcap - terminal capability data base

SYNOPSIS
     /etc/termcap

DESCRIPTION
     Termcap is a data base describing terminals, used,  e.g.,  by  vi(1)  and
     curses(3).   Terminals  are  described  in  termcap  by  giving  a set of
     capabilities  that  they  have  and  by  describing  how  operations  are
     performed.    Padding   requirements  and  initialization  sequences  are
     included in termcap.

     Entries in termcap consist of a  number  of  `:'-separated  fields.   The
     first  entry  for  each  terminal  gives the names that are known for the
     terminal, separated by `|' characters.  The  first  name  is  always  two
     characters  long  and  is  used by older systems which store the terminal
     type in a 16-bit word in a system-wide data base.  The second name  given
     is  the  most  common  abbreviation for the terminal, the last name given
     should be a long name fully identifying the terminal, and all others  are
     understood  as  synonyms  for the terminal name.  All names but the first
     and last should be in lower case and contain no blanks; the last name may
     well contain upper case and blanks for readability.

     Terminal names (except for the last,  verbose  entry)  should  be  chosen
     using the following conventions.  The particular piece of hardware making
     up the terminal should have a root name chosen, thus "hp2621".  This name
     should  not  contain  hyphens.  Modes that the hardware can be in or user
     preferences should be indicated by appending a hyphen and an indicator of
     the  mode.   Therefore,  a "vt100" in 132-column mode would be "vt100-w".
     The following suffixes should be used where possible:

     Suffix      Meaning                                     Example
     -w          Wide mode (more than 80 columns)            vt100-w
     -am         With automatic margins (usually default)    vt100-am
     -nam        Without automatic margins                   vt100-nam
     -n          Number of lines on the screen               aaa-60
     -na         No arrow keys (leave them in local)         concept100-na
     -np         Number of pages of memory                   concept100-4p
     -rv         Reverse video                               concept100-rv

CAPABILITIES

     The characters in the  Notes  field  in  the  table  have  the  following
     meanings (more than one may apply to a capability):

     N      indicates numeric parameter(s)
     P      indicates that padding may be specified
     *      indicates that padding  may  be  based  on  the  number  of  lines
            affected

     o      indicates capability is obsolete

     "Obsolete" capabilities have no terminfo  equivalents,  since  they  were
     considered  useless, or are subsumed by other capabilities.  New software
     should not rely on them at all.
