Re: [hylafax-users] problems with Multitech Modem MT 2834ZDXb

[Karl Denninger <karl@xxxxxxxxxxxxx>]

Those modems NEVER worked right in fax mode. 

I have a handful which were purchased with the intent of using them with 
Hylafax and they were all pieces of crap; essentially unusable in Class 2
mode.  Multitech never helped me even when they were "current product", and 
I have as a consequence written them off as a fax modem supplier.

Their "not current product" is a nice line, but the truth is that they
refused to fix the problems even when they WERE current product!
