Ummm ... sorry about this, the version of PUTR (V1.21) that was available
for FTP up until 10 minutes ago had a bug where it would refuse to copy
the last block of a TU58 tape (foolishly thinking you were trying to
read off EOT).  Fixed now, the new version (V1.22) also adds a "/SEGMENTS:n"
switch to the RT-11 "INIT" command to override the default # of dir segments.
It also has bare bones support for SCSI disks, which isn't in the doc file
yet since it could use a bit more work, it doesn't know about RT-11 partitions
(it wants to use the whole disk as one volume) and can't handle sector sizes
other than 512 bytes.

But if you want to play with it, the SCSI support requires an ASPI driver,
and the MOUNT command looks like "MOUNT ddu: SCSIht_l:", where h is the
optional letter (A-Z) giving the host adapter (default=A), t is the optional
number (0-7) giving the SCSI target # (default=0) on that SCSI bus, and l is
the optional (leave out the "_" too if you leave out l) number (0-7) giving
the LUN of the drive within that target (default=0, in practice probably
never used in practice, but the old Adaptec bridge boards allowed >1 LUN
per target).
