For a friend of mine, who hasn't network access, I would like to ask two questions concerning some problems he's got using TOPS. First of all, let me give you a short description on the environment: In an office there's some 10 PC/XT, a few PC/AT, and a couple of MacIntosh. They are connected to a Apple laser, using a TOPS network. TOPS is only used to create a shareable printer, no file transfer or whatever else TOPS might be able to do is done. Now for the problem: Sometimes, when large PostScript files, generated outside the system, is sent for printing, the printing stops mid-printing. Without any error messages or other kinds of protests. To make the situation even more enjoyable, the same file might fail to print all way thru X times, but make it the (X + 1):th time. (This indicates that there's no syntactical/semantical errors in the PostScript file.) I get the impression of a flow-control problem. That the time between sending a XOFF (or whatever it is on a TOPS net), until the transmission actually stops is to long. Another problem is this: If you request the printing of more than Y files at the time (Y > 10?), the request are all accepted, but only some (<= 10?) are accepted. To make the situation almost perfect, TOPS is furnished by one party, the network cables by another. They both blame the other. Now for the questions: Problem 1: Is there anyone out there who has experiensed any problems like these? If so, has anyone been able to do something about it? Problem 2: Should it really be like this? Shouldn't you get some kind of warning when the queue is filled? Is it possible to get warnings? Gratefull for all the help I can get, I'll pass it on to my friend. ---------------------------------------------------------------------------- International: Domestic: Mats Lofstrom Mats L|fstr|m ENEA Data Svenska AB ENEA Data AB Nytorpsvagen 5b Nytorpsv{gen 5b Box 232 Box 232 S-183 23 TABY 183 23 T[BY Phone: (+46) 8792 - 2500 Tel: 08 - 792 25 00 e-mail: uunet!mcvax!enea!mla or mla@enea.se
