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

19 (0x13)

All GEMDOS versions

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

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.

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.

Cauxin(), Cauxis(), Cauxout(), Bcostat().
