Irda Dial Up Problem

I am trying to connect to the internet via a cellphone.

I tried with a Nokia 6210 and a Nokia 7650.

I like to use a CSD connection not a GPRS connection.

I tried first with a ATDT initstring. That does not work at all.

Then I tried with empty initstring. That does not worked with the Nokia
7650 at all too. The Nokia 6210 started to dial the number I entered, got a carrier but hangup later. Down there you see the lines from file /etc/ppp/connect-errors:

Nokia 7650 with initstring ATDT:

/tmp/qpe-pppd-log:

without initstring I get

... send(ATDT+49177123100)

not

... send (ATDT)


In /etc/ppp/connect-errors:

or again

... send(ATDT+49177123100) without initstring

The phone did not dial!
