Syntax

WORD Cauxos( VOID )

Function      Cauxos() indicated whether GEMDOS handle 2 (normally device
              'aux:') is ready to receive characters.

Opcode        19 (0x13)

Availability  All GEMDOS  versions

Binding       move.w   #$13,-(sp)
              trap     #1
              addq.l   #2,sp

Return Value  A value of DEV_READY (-1) is returned if the output device
              is ready to receive characters or DEV_BUSY (0) if it is not.

Caveats       This function actually returns the status of whatever device
              GEMDOS handle 2 is redirected to. In addition, some 'C'
              compilers use this handle as a standard error device. It is
              therefore recommended that Bcostat() be used instead.
