Hi Lior,

Not sure but may be intention is to say that it supports Null Modem
only i.e. transmit and receive line crossed (http://en.wikipedia.org/
wiki/Null_modem)

Hi VKG,

Why would a software need to know if the lines are crossed or
forwarded through a real modem?

Thanks
Lior

Hi Lior,

I agree that software should not worry about hardware lines but I was
wondering if that can affact the initiation of ppp session. A quick
hit on google search (http://www.tek-tips.com/viewthread.cfm?
qid=1063648&page=1) seems to have answer to your query. Looks like
software depends upon how the session is initiated.

You first need to estabilish the connection with the other modem
(dialing) so you need to send the AT commands to the modem (I think
that using fprintf is good enough), after this you should start PPP on
the same line (I'm using PPP on 6.5 so I can't help you with this)
