Modem connection between two local PCs

Hello everybody,
I didn't know were to post this, so i posted here in hardware section.

I'm having some troubles while trying to interconnect two pc's via modem (soft fax modem, RJ-11 jack). One is a Handheld PC (HP Jornada 728) with a single fax modem slot, and the other computer is a PC with a two-slots fax modem (in/out).

I connect a phone cord to the HPC jack and the other end to the "in" jack of the PC's modem. My problem is that the connection requests me a PHONE NUMBER to dial, but, since it's a direct local connection between two computers, there's no phone number at all. I've tried everything, connecting to the "out" phone jack, connecting a phone line to the "in" jack and dialing its number from the HPC, dialing numbers such as "1", "123", hyperterminal, minicom, AT commands like "atd" and "ata" on the other end getting "NO CARRIER" as response after modem characteristic sounds, etc. And nothing seems to work.

Indeed, i read something about using a line simulator to get the phone cord a determinated voltage and amperage to one of the cables (the geen one) to fake a phone line. I constructed the simple device it displayed in the article, and couldn't get it working.

Could someone tell me or guide me on how to stablish a successful connection between this two computers via modem? Like how should i connect the modems and how to configure them.

The PC has both operating systems, Windows and Linux, i'd prefer the setup from the Linux environment, but if you could make it from Windows, excellent for me too.

I need to transfer data between the two hosts and is possible, share PC Internet connection with my HPC. The fact is that my HPC doesn't have other way to connect (no serial cable, no USB cable, no PCMCIA network cards, ...) So this is my last resort.

Any help will be appreciated.
Thanks in advance.

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
