- I've been doing some work with a SCSI-connected Epson scanner. I have some code
- which is beginning to look pretty good wrt the Epson. It is possible, however, to
- get the scanner in an error state (error code E-1 on the scanner - protocol
- error). When this happens, only powering the scanner off/on will resert this.
- Sending the scanner an initialize command (or anything for that matter) results
- in a SCSI error.
-
- Now when the NeXT boots, the system is doing some sort of reset to each of the
- SCSI devices. I presume this is some sort of low-level SCSI reset command. I'd
- like to have some means to reset the device to recover from this error state. I
- did not see anything in ioctl.h and in a few other includes. I'd appreciate some
- mail from anyone who can give me some leads (Jiro??).
-
- Thanks in advance!
