Serial port datareceived serial#
This is a protocol issue, but serial ports do not have protocols by default, they are character mode devices, which means that they have a send/receive granularity of 8-bits, and has nothing to do with text, or ASCII vs. Unfortunately, the PIC simply does not have enough clock cycles to concern itself with formatting and converting data to support a protocol that it was not designed to support in the first place.) I doubt it has anything to do with the virtual nature of the com port, either. (I mean they are fantastic, but they are far more useful sending raw data than pushing out text that must be converted on both ends. I assume that you are sending raw data from the PIC. You want a binary stream, and it appears that you are getting a text stream. The Encoding member of the SerialPort class might be the place to make the fix. I agree that the value 26 in the stream might be the issue.
Serial port datareceived code#
(It makes it possible for you and I to produce useful code without being a large development house, which is not good capitalism, apparently.)
Serial port datareceived software#
The fact that there already exists a generic IO path for hobbyists is not in keeping with OEM software development. They probably won't, since a lot of Process Control and Instrumentation still uses them, and they are simple enough to get supported in peripherals. Also, it is likely that the serial port is so old that it is assumed that they will disappear soon, anyway. NET, although dumb terminal emulation is likely a clever idea that someone had as a sort of stopgap measure. Probably, the hobby-like use of com ports is not something that was high on the list of compatibility for. (I am unable to investigate it properly now, but there must be a way to make it quit filtering the receive like that.) You might try catching it in the ErrorReceived handler, and eating the EOF, but that looks like a kludge to me I can't say that I like it as an answer at all.
Serial port datareceived windows#
But I do pontificate about serial comms a lot.because I have alot of experience using them in Windows and DOS, and this type of issue you have is a subtle one that they must be aware of. A better class would have a class derived from it that specialized in dumb terminal communications.) Microsoft never asked me what I thought, however. The SerialPort class has no business making assumptions about the data itself, unless it has the capability to implement a protocol, which it doesn't.

Please can anyone give me a reason why this is happening? Thanks I went through the forum and realised that the EOF eventtype is no longer supported, is this true? I dont think that getting this eventtype is logical anyways in my case. When the datareceived event fires with EOF, the Read function blocks until one byte arrives, reads it and calls the function that processes the data. I am using the Read function to read the bytes from the serial port and the Newline property is set to "" (but i thought that this is irrelevant if im not using ReadLine). I have run the program and it seems to read the USB device "correctly" but when i debug the code, i realise that the datareceived event of the serial port gets fired on the eventtype = EOF. The USB device sends a fixed number of bytes and i have set the threshold received byte property to this value. The USB device is a communication class device and thus will emulate the usual rs232 serial port once attached to the PC. NET 3.5) to write a program that communicates with a USB device.
