Please help help with saplogon.ini

Hi experts,

I'm a newbie to SAP. Could you help me to explain the purpose of saplogon.ini and all the parameters of it?

( [Configuration], [EntryKey], [Router], [RouterChoice], [Server], [Database], [System], [Description], [Address], [MSSysName], [MSSrvName], [MSSrvPort], [SessManKey], [SncName], [SncChoice], [Codepage], [CodepageIndex], [Origin], [LowSpeedConnection], [Utf8Off], [EncodingID], [ShortcutType], [ShortcutString], [ShortcutTo], [ShortcutBy], [MSWinPos] )

What are their meanings?

Regards,
