Serial Port open hanging

V

vsciw

Hi.

we are using a symbol mc70 device with GPS, running wm6.1, and we have
written an app in vb.net that opens the gps com port to capture the
data. the hardware port is set as com8, and the program port is com9.
we had problems using the standard serial port classes to open and use
this port, so we used the opennetcf.io.serial.port classes which work
fine the vast majority of the time.

occasionally (it's very hard to reproduce) the port.open function
thread just disappears, and doesnt return to the calling app so it
hangs. sometimes it's the first time it opens the port, sometimes it
opens the port fine initially (our app keeps checking for data coming
through the port and closes/reopens it periodically) but after several
close/opens it hangs.

another device reboot normally clears it.

has anyone had similar experience with this and could suggest
something for us to try and resolve it??

thanks in advance.
ian.
