I recently upgraded my old gvp impact scsi controller to the new series 2 controller. I'm wondering if that was a good idea, I have been experiencing a few problems, some of which may have existed before, but I don't think so. problems as I see them, when there is heavy i/o on the scsi bus, interupts generated from the serial.device seem to get ignored. since I have an asdg dual serial board I figured I'd try that board, same problem, interupts get lost, thus a loss of data, I have tried running the serial port as low as 2400 bps and as high as 19.2K same problem exits. I have been trying to use BTNtape with limited success, I have sent the author several message detailing what has been happening so far, and he has been more than helpful (thanks bob) seeing as running a tape drive on the scsi bus in my opinion although may not be driving the bus to its full speed potential, it is a constant stream of data in or out plus the data from the drive, again the serial ports are worthless when the tapedrive is running. ok, I thought that the problem might be with BTN so I tried using GVP's software for the tape backup unit called "tapestore" same problem, worthless serial ports. at this point I have basically narrowed it down to the problem with gvpscsi.device personally, I wouldn't doubt that their driver (gvpscsi.device) is causing serial.device interupts to be lost seeing as this was a problem with an old rom that they shipped with their 3001 boards to handle the AT style drives. (if you interested, the rom was "AT v2.0") well, it now looks as if a call to GVP is now in order, does anybody have any other theories? anybody experiencing the same problem? anybody know how to slove this problem?? anybody have any suggestions for a new scsi controller??
