in past I solved problem with my Novatel Wireless MerlinXU870 but it was under Porteus 1.1_64

Today I am fighting with it again but Porteus 1.2_64. In this version I do not see Internet Dial-Up Tool (KPPP) which was simple for me. I am using Porteus Settings Center->Network Setup and nothing.
What do I do else?
Please help me solved problem.
I am waiting for answer, thanks.
