Hi, I have an application with aquire data from two different data logger via COM ports. COM 1 and COM 2 are opened at the same time and the serial write and serial read functions are in two parallel while loops. It works fine for a while. But after some time COM 1 did not send data any more. If I stop my application and send an other request via hyper terminal the COM port sends the old request from the last serial write of labview. It seems that labview sends the data to the COM port, they are stored in the send buffer but will not be send by the hardware.
I work with labview 5.1.1 and reproduced the problem with Win98/2k/XP. Any suggestions? Thanks, Niko
