I ordered an MNP level 5 modem from a store nearby. They came up with a 
PcWorks modem that is claimed to be MNP level 7. The thing had only one
flyer of documentation, and nothing was mentioned there about MNP.

Now my questions:

1) I understand that MNP level 4 stands for error-correction
protocol, and level 5 adds data compression. Am I wrong?

2) Is level 7 a super set of level 4 and 5?

3) How can I check what level the modem is? I have currently no computer
to test it with.

4) Can a price of 116.48$ be right for 2400 baud mnp level 7 modem or is
it another "sales person idea"?

I would appreciate any help, and if at all possible before monday, because
I promised an answer to the shop by then.


	Many Thanks!
