Although I cannot test how DSZ might work in conjunction with sz and rz
on a unix (or linux) host via a _local_ dialup, I have tried DSZ from a
shell to DOS in Net-Tamer (Alt-S). DSZ will load in the shell and in my
case DSZ is set to use the same parameters as Net-Tamer (115200, 8-N-1,
COM2), so it doesn't interfere with the port. I used this command line
with dsz: dsz t
That puts DSZ in terminal mode with automatic zmodem download, which is
probably what you'd want when connecting to a shell account to download
a file. You'd want to initiate the file transfer in the unix shell
using "sz (filename" and _then_ do Alt-S to get to your DOS shell in
order to execute "dsz t" to bring up DSZ and start (or try to start) the
automatic zmodem download. Only someone with a shell account at his/her
ISP could test this to see whether it works, but so long as it is not a
telnet connection, it might just work, for downloads and even for
uploads (rz on the unix host and dsz sz (filename) on the local PC). I
hope someone tries this just to see whether it will work.
Unfortunately, my need for zmodem is in telnet and when connected via
telnet, although DSZ will not crash the telnet connection or cause any
problem with PPP, it comes back with a an error message that an 8-bit
transparent path is required. That's also in the documentation for DSZ.
It is a fact that _telnet_ is 7-bit and not designed for 8-bit file
transfers, but other telnet clients have _integrated_ zmodem that works
with telnet. Netterm in Windows works okay for zmodem downloads, though
I've never tested it for uploading (sending) a file to a host.
If ftp is available that is _way_ better for downloading files with
Net-Tamer.
