hi all, sorry for this ot posting. but you guys/girls may know a hint to my questions. I need to code an application that acts like an interface to a router that is connected via com port. under windows this is done with hyperterminal, which uses the xmodem protocol I think. can you tell me, where I can find a good starting point to do this? (communication to com, using the right protocol..) thanks a lot! regards /Christian mailto:caefer@xxxxxxxxxxxxxx --- I propose that the following character sequence for joke markers: :-) 19-Sep-82 11:44 Scott E Fahlman
