 	This is a compatibility hardware problem.
 
 	Versions:
+	0.12c	fixed other multiple cards bug and other cleanups
+		(aris, 08/21/2000)
 	0.12b	added reset when the tx interrupt is called and TX isn't done
 		and other minor fixes. this may fix a problem found after
 		initialization that delays tx until a transmit timeout is
