I am trying to help out a friend with a data transfer

simplify his business. The goal is to move a couple hundred Megs of
data from a PC to a PDP11. Currently he has a DOS box with a Pertec
controller, which he uses to copy data to a 9 track, and then pulls
off on the PDP. This seems... inelegant, I can only assume there is a
simpler way.
Is the data really going from a PC to a PDP-11?
I guess if you are talking just a few hundred megs that's
maybe only ten magtapes or so (GCR?) in which case doing
a bit of tape swapping is probably going to be finished
before you can even configure another solution. Especially
if you have N tapes and can have the source machine
continually writing and not having to wait for the target
machine to finish with the only tape.
Otherwise you probably should look at FTP (if you have
an IP stack for your PDP-11 OS), or FAL (if you have
DECnet for your PDP-11 OS) or Kermit.
Another option might be to write data to a disk and
transfer to the disk to the PDP-11. This assumes that
you have a disk that could plug into both (SCSI is
the likliest option these days) and that one end can
encode data for or decode data from the other end.
You might even find that SIMH or E11 come in handy
for this particular exercise.
