However, there is no reference to this feature in that section. The 7.0 manuals do state that this feature is supported for: 7942, 7946, 7941CT, 9144A and 35401. Question: does tcio(1) support this capability in 6.2 and 6.5 (i.e. is the manual page incorrect or was something added to tcio(1) in 7.0)? Philip Webster hplabs!hpuepta!attila!pw P.S. I discovered a convenient way to block until a tape is loaded especially nice for our 35401 in seq. mode for producing our software. #! /bin/csh set src_loaded = 0 while ( $src_loaded == 0 ) sleep 30 tcio -i -S 8 /dev/update.src |& dd bs=1k count=1 >& /dev/null if ( $status == 0 ) then src_loaded = 1 endif end
