It sounds like you need to make use of "ModemGroup"-ing.  So when a user 
submits a "broadcast" fax make sure that it gets submitted to a certain 
ModemGroup that does not consume all of your modems (i.e. the default 
"any" ModemGroup).

So in your /var/spool/hylafax/etc/config file (faxq configuration) you 
put something like this:

 ModemGroup:  broadcast:ttyS[0-2]

Then when the broadcast faxing is sent for the user make sure that the 
"modem" (ModemGroup) is specified such as this with sendfax:

 sendfax -h broadcast@ -z list faxfile.pdf

Thanks,

Lee.
