[hylafax-users] Bad 1D/2D pixel counts and invalid code words

["Dennis Fellows" <dennis@lamtop.com>]

Well, I upgraded to beta3 with no prob and set my session tracing to 0xFFF.
I haven't experienced any Faxgetty hangs (yet)!

I've got some questions as to what the errors are. I waited for at least
three faxes to come in to make sure that the errors were typical (they
were). Now, I know that I may be dealing with line noise (I've given up
fighting with my local telco (Ameritech) and am moving to a local T1 from
another phone company) but I want to make sure these errors are not config
errors. Here is a typical log with my questions interspersed (**)....
