Yes.  Actually, support for these features really depends on your 
destination pool.  Pools of older or perhaps cheaper fax machines will 
almost always support fewer features than pools of newer, more 
expensive ones.

HylaFAX would hang up, reformat, and then call again with an 
appropriate format.  However, HylaFAX faxq will not normally prepare a 
hyperfine document to be sent to a destination unless it knows that the 
destination supports it.

This would be a type of on-the-fly resolution conversion, and HylaFAX 
doesn't do that.  Shrinking images and keeping them looking good can be 
tricky... so we leave that up to Ghostscript, since they're the imaging 
experts.

It would abort and then retry.
