I just obtained the zmodem programs sz and rz from sonata.cc.purdue.edu
and now I have a few questions. First some background: I've used
sz and rz before using a PC (dos) machine as the local machine and
a UNIX(tm) machine as the remote machine. This worked fine since
I could use add zmodem as an external file transfer protocol on the
DOS side. After executing sz on the UNIX(tm) side, I could escape
back to the local machine (DOS) and execute rz. This appears to be
much the same way the kermit works between two UNIX(tm) machines
(i.e. issue a "kermit -s filename" on the remote side, type control-/C
to escape to the local side and type "receive").
Given all this, I wish to use the same technique to transfer files
between my NeXT and another UNIX(tm) machine using the zmodem protocol.
I've tried using tip and sz/rz together with the ~| or ~$ options but these
options don't appear to work (at least under NeXT 1.0 they don't). I think
they don't work because tip is setuid to root and the ~| option
involves executing a shell (this would be a security hole, yes?).
So I guess my question is: what is the NeXT equivalent of Procomm as
used in the scenario in my first paragraph? (I also tried using Pcomm
as available in the comp.sources.unix archives but it is a System V
specific program - it uses the termio ioctls).
I'd really like to use zmodem because it is MUCH faster than kermit in
my experience.
Thanks...

By the NeXT equivelent to Procomm, I assume you mean, "What's cheap, ugly, but works." Well, your in luck. I wrote HitchHiker (you should get version 1.1 from cs.orst.edu) about a year ago to do just that. The bad news is that I am now working on Microphone so I am unable to support HitchHiker in any way shape or form. (Maybe I can still answer real simple stuff, but nothing to complicated, I don't even own a copy of it anymore). -- Michael Rutman | moose@svc.portal.com Cubist | makes me a NeXT programmer Software Ventures | For Your Eyes Only Public Key
