You could try to leave it to ppp, just for testing purposes.
Everything you need is a number you can dial. Here's an
example for an /etc/ppp/ppp.conf that would do something
like this:

# --- ppp.conf -----------------------------------------------
        set log Phase Chat LCP IPCP CCP tun command
        ident user-ppp VERSION (built COMPILATIONDATE)
        set device /dev/cuad0
        set speed 115200
        set timeout 120
        enable dns
        set phone PHONE_NUM
        set authname USERNAME
        set authkey PASSWORD
        add default HISADDR
        set phone 0123456789
        set authname QWERTZ
        set authkey ASDFGH
        add default HISADDR
# --- ppp.conf ----------------------------------------------- end ---

With such a file, you can now:

	# ppp test
	ppp> dial
	*click dit dit dit dit... dooooo doooooo... *
	PPP> close

In this case, you have confirmed that the serial modem works as
intended. You can of course enter real data for an ISP that offers
modem dial-in to get online. :-)

You can find more help and examples in "man ppp".

But it IS a modem to dial tones and connect to something?
"Net search"... no idea what that could mean. Serial modems usually
don't search for nets...

Or am I completely misunderstanding you and you're trying to find a
command access to a DSL modem that has a serial line?
