[] Does anybody have the TU80 streamming on UN*X ??? How about a modifcation to tar with big buffers or the like? Any help would be greatly appreciated. Our configuration: UNIX 4.2 BSD, VAX 750, RA81, RA80, TU80, Futjisu Eagle Thanks in advance Dale Anglin Management Decisions Development Corp. 7209 Dixie Highway Fairfield, Ohio 45014 (513)874-6464 ...{ucbvax,decvax,inhp4,mhuxi}!cbosgd!mddc!dale (uucp)

Getting the TU80 to stream on VMS requires the user to tell the system to allocate 5 buffers. There's no way on Unix to do that, at least not using the raw interface, where I/I is synchronous. I've considered says around this, e.g. to add buffering to raw transfers, but I'm not happy with any of the solutions I've come up with. Their general flaw is that they change the semantics of the raw tape interface somewhat. It's not too useful, but using blocked tape the TU80 will stream. The disadvantage, of course, is that you can only get 2k byte records. -- Ed Gould {ucbvax,decvax}!mtxinu!ed
