* Runtime environment for the BASIC interpreter, the
* hardware configuration file. It contains all hardware
* related settings and dependencies.
*
* This is hardware.h for POSIX systems and the POSIX runtime
* environment runtime.c.
*
* Default setting is POSIX for most UNIXes including Mac.
* RASPPI activates Raspberry PI related features.
* MINGW activates windows related features.
* MSDOS for MSDOS compiles with tc 2.0 (untested in this version, last tested in 1.4)

/*
* Hardware flags of the POSIX systems
* POSIXTERMINAL, POSIXVT52TOANSI: ensure compatibility of BASIC programs
* control characters of BASIC are translated to ANSI, bringing the Aruino
* VT52 commands to POSIX
* POSIXSIGNALS: enables signal handling of ^C interrupting programs
* POSIXNONBLOCKING: non blocking I/O to handle GET and the BREAKCHAR
* tricky on DOS, not very portable, experimental, use signals instead
* POSIXFRAMEBUFFER: directly draw to the frame buffer of Raspberry PI
* only tested on this platform
* POSIXWIRE: simple Raspberry PI wire code
* POSIXMQTT: analogous to ARDUINOMQTT, send and receive MQTT messages (unfinished)
* POSIXWIRING: use the (deprectated) wiring code for gpio on Raspberry Pi
* POSIXPIGPIO: use the pigpio library on a Raspberry PI
