And for those who weren't aware: the latest version of the driver,
along with a userland utility (complete with man page) are now
documented in Appendix A of the "... zSeries ... Large Scale Linux
Deployment" Redbook and available for download from the redbooks site:
The UR device driver provides a Linux character device interface
to an attached unit record device for a Linux guest. The UR
utility provides a user interface to the UR device driver.
Using the UR driver and utility, it is possible to exchange files
between a Linux guest and a z/VM virtual machine (initiated
within the Linux guest). The UR utility provides an interface
for copying files between UR devices (typically the reader,
punch, and printer defined by the virtual machine). It can
handle any file block size, and record length, and will perform
EBCDIC-to-ASCII conversion as required.
The UR device driver and utility can be downloaded from the
Internet as described in Appendix D, Additional material on
page 279.
For the ur utility, the syntax is:
ur copy [ -tbf ] [ infile | - ] [ outfile | - ]
ur info devfile
ur list
ur add minor devno blksz reclen flags [ devname [ perm ] ]
ur remove minor
with the last two lines providing dynamic device support.
