Just a couple tips: Periods (“.”) go after a sentence but [u]before</u> the space between the sentences. The 1st letter of the next sentence should be capital. The personal pronuon ((“I”) is always capitalized no matter where it is in a sentence.

Does the Port.Writeline have a return value?

I cannot find the method that you are using, but see http://msdn2.microsoft.com/en-us/library/aa918511.aspx
