I hope you do the right thing by posting a summary back to the newsgroup.
(I Bcc'd this to the poster as well as posting it to the newsgroup.)

Assuming that you want to continue using Kermit, but to add z-modem
for file transfers, which is what I did as of a few weeks ago,
what you can do to get started with Z-modem is:

Get the zmodem file transfer software - which is actually called DSZ -
strictly speaking "zmodem" is only the protocol.  Find the recent
version of Nov. 11 '92: DSZ1109.ZIP and install it on your DOS system.

You can call the developer's BBS at 503-621-3746, or look on the simtel
mirror sites, or at:

    ftp.uu.net	/systems/ibmpc/msdos/simtel20/zmodem/dsz1109.zip

Read the big dsz.doc file, which has a section on co-operation between
Kermit and dsz, (amid a wealth of other datacomm & modem info), and
which suggests adding something like these:

define rz run dsz F ha on port 2 speed 57600 pY129 rz -r
define sx run dsz F       port 2              sx 1 2,define 1,define 2,
define sz run dsz F ha bo port 2 pY129 pB4096 sz 1 2,define 1,define 2,
define t  run dsz F ha on port 2 pY129 t  -r
	      ^^^
to your mskermit.ini file, with appropriate changes for speed, port 
& path (dsz should either be in your PATH or specified where the ^^^ is).
Also, add something like these to your autoexec.bat or a specific batch file:

    set DSZPORT=2                 
    set DSZLOG=c:/dszlog

Once you've done that, you can start an 'sz' process on the remote
host, escape to Kermit's command prompt, type 'rz' and stretch a bit
while the files stream in.

A warning: You will probably find several dozen associated programs at
the ftp sites.  All you need for file transfer is dsz - the others are
optional extras.  If you want to check them out, look first at the
recent zip files beginning with DSZ, GSZ, YAM, and ZCOMM, and look for
the "Omen Technology" name as you unpack them.

I may sound peckish about this, but I downloaded (by telnet) and
unpacked about 3 MB of software (because I didn't know which package was
which) only to find that I only needed about 300K of what I grabbed!
If I had had to use a slower download method I might have grabbed less,
but sorting through all the little packages (one of which had zip-files
within zip-files!) was a bit of a pain.

2nd warning - the complexity level in the dsz program, options, and
documentation is high (at least for the typical DOS user, less so for a
long-time Unix user).  The complexity reflects the flexibility and
configurability of the program, and you can freely ignore most of the
complexity, BUT DO look at the 'getting started' and Kermit sections of
the documentation.  Once you get it set up and working the
ease-of-use is also very high.  I am quite satisfied. 

Finally, DSZ is shareware, and I found it well worth spending $20
to register it & support the process.  I hope you do too.
