When printing some labels with the Seiko Smart Label Printer software I've come across a difference when using real serial ports vs a usb to serial adaptor. Printing labels with not much content is fine. But when printing labels with more and longer lines of address via a real serial port only about half the label prints. There is no obvious errors encountered and from the Queue ...

Boy I'm confused, I've opened a serial port connection using: CreateFile(portName, (GENERIC_READ | GENERIC_WRITE), 0, 0, OPEN_EXISTING, FILE_FLAG_OVERLAPPED, 0); and read data using ReadFile(), WaitForSingleObject() and GetOverlappedResult(). The device I'm communicating with, responds to a certain command by returning 10-20 bytes of information immediately, then pauses for awhile while ...

I would like to use the instrument IO assistant to send a trigger command to the controller (in ASKII) and write the data received back to a file. The data received from the controller can be ASKII or binary. I have set...

Hi guys, thanks in advance for your help This is the scenario: I am writing a program to make all the serial ports on a PXI box is working. When the check is performed, the serial port wont be connected to any thing, so I guess I probably can't do a loop back test. So how can I do this? ...

Hi, Is something else connected to the device? If so you can open a session and try to ping the connected device (*IDN? Or some other basic command and then read the response). If nothing is connected you can open a session to the com port and look for errors on the error line. This last suggestion, as LV_Pro mentioned, is not as good as an actual loopback because you miss the ...

I somehow managed to learn how to send data using serial port control and set parameters like baudrate , stopbits , etc. But I' not getting how to get the received data...

I'm using several forms, each requiring access to the serial port. When I switch between them the port is deactivated. The port is activated through a special library command. How can I keep the port open and provide access for the other forms? I'm reopening the port triggered by form_load for form2 but that only works when I go to form2. When I come back to form1 the form_load trigger...

vitamin linux kernel bug 12309 is mostly likely part the locks and part this http://thread.gmane.org/gmane.linux.kernel/888279 Ie the write back system not working either.
