If the * expands to more than one file, that may cause problems.

NAME
faxanswer - tell a HylaFAX server to answer the telephone SYNOPSIS
/usr/sbin/faxanswer [ -q queue-dir ] [ -h how ] modem DESCRIPTION
faxanswer sends a message to the HylaFAX faxgetty(8) process servicing modem telling it to answer the telephone. This is useful, for exam- ple, when a modem is used on a shared phone line and the server is configured to not normally answer the phone. The specified modem can either be the name (typically the last component of the terminal port the modem is attached to), or the full name of the associated FIFO named pipe file, e.g. ``FIFO.ttym2''. OPTIONS
-q dir Use a spooling area other than /var/spool/hylafax. -h Specify exactly how the phone should be answered. By default, the server process is instructed to answer the phone and accept any kind of call (voice, data, fax). Discrimination of the type of call is dependent on a modem's adaptive-answer support. The -h option can be used to force the server to answer the phone for particular type of call: one of fax, data, voice, any, extern (to force faxgetty to invoke an external application to to handle the call), or dialX (where X is a dialstring to dial before initiating a fax reception). If using dialX, the specified dialstring will likely need to end with a semicolon (``;''). FILES
/var/spool/hylafax default spooling area /var/spool/hylafax/FIFO fifo for contacting faxq Consult hylafax-server(5) for a complete discussion of the structure and content of the spooling area. SEE ALSO
