This is not true, since I use an A3000 myself and have got this problem with a USR HST and an ASDG dual serial board that I have stuffed into the machine. Even when running the commsprogram at a high priority and transferring to RAM:, I do get errors as soon as I activate a window or list a directory on my harddisk. I do use CTS/RTS (and know that it works, have even tested this with different switches). I haven't tried using the internal serial port but I expect the same things happen then. Oh by the way, I have connected two hard disks to my machine. Perhaps this could be causing trouble? I read that Jack Radigan had been doing some tests proving that this will cause problems. Having more than one harddisk connected to my A3000 certainly DOES cause problems with this machine. My machine locks up many times every day when saving something onto a harddisk, often in the middle of the file, causing me many hours of extra work. Yes, I _have_ turned off reselection and have double-checked the hardware (got a brand new motherboard a few days ago, with the same problem). I am now in general so fed up with my A3000 that I wonder if I should switch to my good old A2000 (which didn't have these problems at all when using multiple harddisk). I use KickStart 37.21 so these problems *should* be fixed now. I hope some responsible person is able to kick some a...s if something isn't done really soon. A friend of mine has exactly the same problems with lockups during writes when using more than one harddisk. If this is not a software problem, there must be a serious bug in the SCSI chip. /- TL -/ (A multitasking OS without MMU support? Just say NO!)
