Terminal and dial up problems

[Tom O'Donald]

Hi.
As as new user of Ubuntu I have run up against two problems.  Firstly, 
everything I have read refers to a "Terminal" box under the system menu.  I 
have Ubuntu 7.04 and this is definitely not there.  Is there a substitute 
location or is it possible to install this?
My other problem involves connecting to my ISP using a dial-up modem.  I have 
purchased an external modem (Dynalink) which is recognised by Ubuntu and 
through which I can dial up.  However within 0.5 to 2 seconds the connection 
drops out.  Can anyone possibly help me out?
