If your receiver here really does support high resolution then the Diva 
Server is preventing you from seeing that.  Realize that the Diva Server 
kind of acts as a fax proxy - so you can't completely trust that the 
picture that the Diva Server presents to you is the same picture that 
some other device may let you see.

Anyway, according to the Diva Server's responses here the remote does 
not support anything other than normal resolution.

Also, notice the "T.30 Annex C" claim there - it's incorrect, no doubt.  
So it would seem that Eicon has changed things in that regard to more 
correctly meet the Class 2 spec (instead of the Class 2.0 one).  It 
won't help you for this resolution issue, but you should change your 
modem config file to use:

 Class2ECMType: 2

(Or just remove the "Class2ECMType: 2.0" line entirely.)
