A new version of PUTR.COM, a copyrighted but freely distributable program for
accessing DEC filesystems from MS-DOS, is available via anonymous FTP from
tats.wizvax.net, pub/putr/*.  Assembly language sources are included.

The major addition since V1.02 is the ability to initialize and write files
on OS/(27)8 volumes (the previous version could only read them).  Note that
while the new code is believed to work correctly, it has not had extensive
testing so please be doubly sure to make backups before using PUTR to write
on volumes containing important data.

PUTR supports the following file systems:
OS/8, OS/78, OS/278
RT-11
RSTS/E 0.0, 1.1, 1.2 (read only access)

Media:
DOS container files (containing byte-by-byte or block-by-block disk image)
RX50 floppies (in PC 1.2MB drive)
RX01/02/03 workalike floppies (in PC 1.2MB drive)
RX01 floppies (in 8" drive attached to PC FDC -- untested)
TU58 cartridges (using real TU58 attached to PC COM port)

LD: container files are supported in RT-11 volumes and are made to look like
a hierarchical directory system.

PUTR can format all the floppy disk types it uses (N.B. many PC FDCs don't
have working single density support), and the RX01/02/03 workalike disk
format is compatible with that used by the RX211 emulation in Ersatz-11.

PUTR also has a WIPE command for writing zeros over unused areas of RT-11
or OS/8 volumes, for better compression with GZIP or Kermit or whatever.

PUTR is named after the PUTR.SAV utility that runs under later versions
of TSS/8.  The name stands for "peripheral utility transfer routines".
