yep a 'nix command line greybeard. was hoping to avoid the alias
route but ok if that is the only way to do it. i tend to create
'em and then, especially for low use cmds, forget all about 'em.
i'm still confused by your explanation of the man page statement
about options. it looks to me to be an artifact (the statement)
from maybe a parallel or scsi backend manpage. i'd take a stab
at fixing [improving] the rof text if i had a better understanding
of what the genesys backend really supported.
thanks for your reply and sending my query thru to the mail-list.
