[Pete Holsberg ('s', not 'z') wonders about the DSZ program by Chuck
Forsberg.]
The documentation that was packaged with DSZ has, buried deep in its
getting-started-hints section, instructions for running DSZ standalone.
The major value of this is to convince oneself that DSZ is in fact
working. It's not much as a terminal emulator; doesn't act like any
particular terminal, as I recall. But it does work.
I use it as an "add-on" to Procomm v2.4.2, via Mark Herring's POE
utility. (I invoke the "editor", ctrl-A, which starts POE. This gives
me upload/download menus, and I've installed DSZ in them.) ProcommPlus
has this "add-on" feature built in, I understand... anyway, my poe.cfg
file specifies the following commands:
DSZ sz ! to prompt for a filename, then send it
DSZ rz if I've already done an "sz" command on the host
DSZ d t invoke DSZ as a terminal (then I can do the "sz"
command to the host, and DSZ picks it up)
From the names given to the options, it's obvious that DSZ was written
specifically with sz/rz in mind.
Final comment: I haven't been able to convince myself that dsz & zmodem
is faster than the ymodem-batch option that Procomm has (and which rz/sz
also supports, more-or-less transparently); I also can't convince myself
that it ISN'T faster. It seems a bit niftier, somehow, but getting it
started takes 3 keypresses which respond marginally slower (on my XT
clone) than the 2 that Procomm takes. I haven't registered it, because
my usage of it is still "experimental" -- it works, but what is it
really doing for me that my registered Procomm isn't?chip@ateng.ateng.com (Chip Salzenberg) (01/05/89)
According to grandi@noao.edu (Steve Grandi): >I have never been able to get reasonable performance out of the dsz-sz/rz >system when I'm using a 9600 directly connected terminal line. > >On the other hand, YMODEM Batch using 128 byte packets works fine [...] The "rz" program, if invoked as "rb", does Ymodem Batch protocol instead of Zmodem. Likewise "sz" if invoked as "sb". No need for another XMODEM program. -- Chip Salzenberg <chip@ateng.com> or <uunet!ateng!chip> A T Engineering Me? Speak for my company? Surely you jest!
