The P.C. will not resend the byte, if there was a byte in transit when you sent out the Xoff you will need to receive it or ignore it as the case may be. Your code should be written so that you acquire input data during the time that you are sending data, (E.G. between sending bits you receive bits). If you are doing this then you won't loose anything. This is one argument for interrupt driven comm but it is certainly possible to structure your code so as to send and receive at th same time. >Wouldn't it be lost, or does the PC resend that possibly lost byte the next >time it receives an Xon? > >- Keelan > >---------- >>From: Dan Welch - W6DFW >>To: PICLIST@MITVMA.MIT.EDU >>Subject: Re: UARTless & Interruptless RS232 flow control >>Date: Sat, Jul 1, 2000, 9:59 PM >> > >>At 09:13 PM 7/1/00 -0600, you wrote: >>Configure your PC for Xon/Xoff flow control you then send an Xoff, (Ctl >>S), to stop the data flow and a Xon, (Ctl Q), to restart the data flow. >> > >-- snip -- > >> - Dan Email: dan@byonics.com >> >>See the GST-1 Converter for Earthmate GPS units at: >> http://www.byonics.com/gst-1 > >http://www.piclist.com hint: The list server can filter out subtopics >(like ads or off topics) for you.
