[hylafax-users] Beware TeleZapper

[Boris Michael Kokodyniak <bmk@xxxxxxxxxxxxxxxx>]

Beware that sending to a fax machine with a TeleZapper can cause 
mysterious send-fax failures like this one:

Apr 17 00:49:28.26: [ 2837]: DIAL 4165551234
Apr 17 00:49:28.26: [ 2837]: <-- [15:ATDT4165551234\r]
Apr 17 00:49:48.00: [ 2837]: --> [5:ERROR]

The problem is not HylaFAX but the modem. Once the remote fax machine 
answers, the TeleZapper will send its tone sequence and fool your modem 
into thinking that there is no valid carrier. Then HylaFAX hangs up.

HylaFAX tries to send the fax again later, and may eventually succeed if 
the modem does not always return an error condition upon receiving the 
TeleZapper tones.
