In a new installation with newly-bought modem (USR 56K external) I
have a difficulty in sending faxes: The modem connects, seems to
finish its negotiaion and transmit the fax, then after a time
announces that it has a FHS:54 error. The recipient fax machine
announces to its owner only "Communication failure".
I have found in the archives of this list a list of fax error codes.
I now understand from the list of codes that the meaning of the
FHS:54 error is that an EOP signal was not acknowledged by the
recipient machine; it is unclear to me if that means it didn't get
one, or whether what it sent back was defective, or something else.
Since the recipient machine has been operating normally for a long
time without problems, and is therefore probably reliable, I am
assuming that the difficulty is somehow at my end. If someone has
some insight into this error, I would be very grateful for any advice
on how to deal with it.
