Reading from tape drive on PC [message #2527]

We are developing a data view program in IDL on a Unix box which reads data
on the fly from an Exabyte tape drive. We have used commands like

openr, unit, '/dev/tape', /nostdio
readu, unit, data, transfer_count = nread

to read blocks from the tape with no problems. However we would also like
to be able to use this program on a PC running IDL, with an Exabyte drive
attached to a SCSI adapter. I do not believe these commands would work
since we cannot specify a device name like we can in Unix. Has anyone done
something similar on a PC in IDL, perhaps using external Fortran or C
routines to get blocks of data from a tape drive?
