They're macros, not functions. #include <osbind.h>. The preprocessor
will convert them go the appropriate GEMdos/BIOS calls.

Note that Sozobon adds a leading space to external identifiers,
so what it can't find is Bconin and C_conout.

(Proper spelling of the GEMdos console output routine is Cconout -- no
underscore after the C.)

Here's a simple term routine that uses only BIOS.

#include <osbind.h>
#include <keydef.h>

#define AUX 		1
#define CON 		2
#define	KEY_UNDO	0x6100

term()
{
	register int c;
	register long d;
	while (1){
		if (Bconstat(CON)){
			d = Bconin(CON);
			c =  ( (d & 0x00FF) |  ( (d>>8) & 0xFF00 ) );
			if (c == KEY_UNDO) return;
			if (c) Bconout(AUX,c);
		}
		if (Bconstat(AUX)){
			c = Bconin(AUX);
			Bconout(CON,c);

		}
	}
}
