* pcvt_conf.h VT220 driver global configuration file

/*---------------------------------------------------------------------------
*
* from: Onno van der Linden c/o frank@fwi.uva.nl
*
* Here's an idea how to automatically detect the version of NetBSD pcvt is
* being compiled on:
*
* NetBSD 0.8 : NetBSD0_8 defined in <sys/param.h>
* NetBSD 0.9 : NetBSD0_9 defined in <sys/param.h>
* NetBSD 1.0 : NetBSD1_0 defined as 1 in <sys/param.h>
* NetBSD 1.0A: NetBSD1_0 defined as 2 in <sys/param.h>
*
* The NetBSDx_y defines are mutual exclusive.
*
* This leads to something like this in pcvt_hdr.h (#elif is possible too):
*
*---------------------------------------------------------------------------*/
#ifdef NetBSD0_8
#define PCVT_NETBSD 8
#endif
#ifdef NetBSD0_9
#define PCVT_NETBSD 9
#endif
#ifdef NetBSD1_0
#if NetBSD1_0 > 1
#define PCVT_NETBSD 199
#else
#define PCVT_NETBSD 100
#endif
#endif
/*---------------------------------------------------------------------------
* Note that each of the options below should rather be overriden by the
* kernel config file instead of this .h file - this allows for different
* definitions in different kernels compiled at the same machine
*
* The convention is as follows:
*
* options "PCVT_FOO=1" - enables the option
* options "PCVT_FOO" - is a synonym for the above
* options "PCVT_FOO=0" - disables the option
*
* omitting an option defaults to what is shown below
*
* exceptions from this rule are i.e.:
*
* options "PCVT_NSCREENS=x"
* options "PCVT_SCANSET=x"
* options "PCVT_UPDATEFAST=x"
* options "PCVT_UPDATESLOW=x"
* options "PCVT_SYSBEEPF=x"
*
* which are always numeric!
*---------------------------------------------------------------------------*/
/* -------------------------------------------------------------------- */
/* -------------------- OPERATING SYSTEM ------------------------------ */
/* -------------------------------------------------------------------- */
/*
* one of the following options must be set in the kernel config file:
*
*======================================================================*
* N e t B S D *
*======================================================================*
*
* options "PCVT_NETBSD=xxx" enables support for NetBSD
*
* select:
* PCVT_NETBSD = 9 for NetBSD 0.9
* PCVT_NETBSD = 99 for PRE-1.0 NetBSD-current
* PCVT_NETBSD = 100 for NetBSD 1.0
