[newbie] Modem problem

[da]

 Hello,

 I am trying to connect to the internet in Mandrake 6.1.  I have a modem
(with plug and pray turned off) on Com4 (as it is called in windows).
 Now there is no dev/modem. So I set the dialler to use com4 (tty3 or
what it is called), it can communicate with the modem but will not
pickup.
 What do I have to do to achieve pickup so it can connect?
 (my modem is a non winmodem that I have got to run fine in the past
with the same settings on another unix)

thankyou for helping :)
