It is certainly not unheard-of for software to requires a line termination (eg, CR and/or LF) before processing a "packet," but I don't think that "most" is justified.
Even hypoterminal doesn't require it! Exactly my point. Any common generic terminal program isn't going to require a CR and/or LF to display serial data--though without an LF you may end up writing on top of the same line over and over unless you have it append LF's. But it seems to me the only reason you'd have to use a CR/LF to get the data to appear is if you're using some custom program--in which case you should know what you need to do to make data appear. VB doesn't have a "GetLine" serial function as it were; it has the piece-of-junk MSComm control which can trigger comm events under certain circumstances. In fact, I don't even think that control can be configured to trigger on a specific end-of-line sequence--rather it triggers the event when the specified receive buffer is full. Disclaimer: That may have changed in VB.NET. I don't dare move beyond VB6. Regards, Craig Steiner |
