[hylafax-users] Using a serial modem through a converter from ethernet to serial

[Davide Pagnin <pagnin@xxxxxxxxxxxxxx>]

	Hi all!

One of our customer is trying to setup a linux server virtualized on 
VMWARE to send faxes.

The main problem is VMWARE ESX limit the support to only serial ports 
and that he has only 1 physical serial port on the physical machine.

To solve the issue and have more than 1 fax connected to the virtual 
server he has ordered a ethernet to serial converter:

ET-BOX-232

http://www.qfp.it/et-box.php

After the installation of the kernel module and the configuration of the 
virtual layer to see the virtual serial device, I was able to launch 
faxsetup on the virtual device and it has correctly recognized the USB 
Robotics modem that was connected the the converter.

But the story is not a success... we are unable to send faxes, the 
device seems to hang.

I've asked for support to qfp and they are willing to help me, but they 
asked me something that I really don't know on hylafax use of the serial 
port:

ITALIAN LANGUAGE:
> tenga presente che il modulo gestisce i segnali tx, rx, rts, cts ma
> non gli altri segnali di controllo
> come ad esempio il CD, RI. Che lei sappia l'applicazione ha bisogno 
di > questi segnali ?

ENGLISH TRANSLATION:
you have to know that the kernel module handle tx, rx, rts and cts 
signals, but it does not handle other control signals, i.e. CD, RI.
As far as you know, the application does need those signals?

So, the question is, does hylafax need CD, RI or other serial control 
signals to properly function?

Thanks in advance

Regards
Davide Pagnin
