I have an application where a call netOpen() and netClose() multiple times within the same process (see below) to create, use, and destroy a session. The first session works fine, however after the second netOpen() call I never receive any packets from the destination device on the network. I tried various sequences with the API that seemed reasonable, but I cannot get the second netOpen() to receive any packets. It may also be the case that the transmit never happens and as a consequence nothing is received from the destination device on the network. Note that netInit() is called once at the start of the application process and netShutdown() is called when the application terminates. Are there any obvious issues with the sequences listed that would prevent a subsequent session from working in terms of transmit and receive?
