I think we came to the conclusion to make something else > than now, but i forgot what it was. :-) We decided that if something claims it is "in the process of becoming ready" we'd keep trying forever with an increasing timeout that stops at 20 seconds or so, together with an ioctl on a control device to force it to finally fail. I don't think it applies in this case. -- Peter Dufault Real Time Machine Control and Simulation HD Associates, Inc. Voice: 508 433 6936 dufault@hda.com Fax: 508 433 5267
