[Dev-C++] Microsoft C 6.0 conversion problem

[<Gen...@ao...>]

Just purchased DevC++ and found that Microsoft's C 6.00 bios and graph=20
functions are not supported.=A0 Are there equivalent functions available for=
=20
mingw that anyone knows about?=A0=20

Bios functions are used (for example) to access the serial port directly.=
=A0 I=20
know about bioscom(), but that isn't supported in DevC++ either.

Graph functions handle a 'pretend' GUI interface for DOS based applications=20
(_setvideomode() is an example of this).

Any input would be appreciated.=A0 Otherwise, I have a significant amount of=
=20
code to re-write for a non-profit group I volunteer for.
Thanks,
