yes this is exactly what I am experiencing.

yes I thought that multitechs were recommended and have used the 2834mr for
a while with hylafax.  Don't remember having this problem with earlier version
of hylafax but am not sure why it is happening now.

correct. sending faxes are fine.  I can even send a fax to the fax machine
I've been using to test in both fine and standard resolutions just fine.
It seems my only problem is in receiving faxes.

do you mean the revision of my modem?  Just upgraded to the latest tonight
and it had no effect.  Also was beginning to think it was because the 
encoding was set to 2d rather than 1d.  I tried setting the
RecvDataFormat:   "1-D MR"   parameter in my config.ttyy2r file but that
did not seem to fix anything as it still received in 2-d.  But I'm not
sure if I turned on copy quality or not for that to take effect.  Will check
into tomorrow. 

Incidentally, I sent an email to multitech support and they wanted to know
the init string of the modem and to include at+frbor=1.  I know the init
string is  ats8=2s7=60&e5&d3&c1  but am wondering how I can add to that
init string.  Where in the config file do you specify what to use for the
init string and how can I add at+frbor=1 to be executed?   I tried the
ModemResetCmd:  Parameter in the config file but that issued the command
before the init string.  Any ideas?

thanks for the reply
