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!
