It seems that "rb" and "sb" are public-domain [Someone please correct me if I'm wrong]. I'm sure both these and "xm" (just xmodem) have been posted to the net recently. But if anyone's missed them and really needs the source we could arrange a non-USENET transfer. -thomas williams UUCP: {psuvax1,pyrnj,cbmvax}!vu-vlsi!williams
