I know there's a few others here who use AsyncPro - so I wondered if anyone can help me with this problem (or confirm that it's a limitation/bug of AsyncPro).

I want to stimultate 4 serial devices simultaneously, and monitor their responses:

I open 4 Ports, and have 4 Timer functions, one for each Port.
The timer functions "ping" the ports periodically, and I have 4 Data Packet instances waiting for the responses - again, one per port.
(I also have 4 Terminal instances to watch the "pings" and responses)

This is the problem: only the first Data Packet ever triggers.
I can see that the "pings" are being sent correctly, and the correct responses are being received - it's just that 3 of the Data Packet instances never trigger.

It works fine if I build a single-port version of the application, and just run it 4 times - but this is inconvenient.

The manual mentions having multiple Data Packets on a single port, but says nothing about having multiple ports, each with a single Data Packet.

Any ideas?

Version is 4.06 - I think this was the last version before TurboPower abandoned the product to SourceForge.

I have also posted this on the AsyncPro forum at SourceForge:
