I recently went through the same nightmare after an upgrade to 2.4.26 on
Slackware 9.1.  I had to go back to 2.4.22, after which I noticed a very
strange problem with ztcfg.  ztcfg would work perfectly, but ztcfg -vv would
immediately lock the box.  I simply rm'ed /sbin/ztcfg, recompiled zaptel and
it appears to be working normally.
