From: Art Berggreen <ART@ACC> Before I start digging into this problem, I thought I'd see if anyone on the net has any ideas. We have an RSX task image which runs fine under VMS 3.x. The task does an ALUN to an RSX device name (e.g. XY0:) and does vanilla READLBLK and WRITELBLK I/O. The native mode VMS driver is named XYDRIVER and devices usually are XYA0:, XYB0:, ... . Under 3.x the ALUN call would either use device spec defaults and expand XY0: -> XYA0:, or if we provided a logical name (either process or system wide) it would associate XY0: -> whatever. Under 4.x the program appears to run ok, but the I/O request doesn't seem to get to the driver's FDT routines (things just hang waiting on I/O). Does anyone know if the RSX emulator has changed in the way it handles I/O request? Could the new logical name support be affecting this (I have tried exec mode names)?
