Hello Steve,

I can consistently receive faxes from am HP5510, but I cannot transmit 
(txfax) at all--it falls over after:

DTC with final frame tag
In state 9
Start tx document
??? with final frame tag
In state 4
   Hangup

I've tried both the stock and text version of app_txfax.c

Is there something I've overlooked?

Thanks for your help,
Mike
