Thank you, Dod... I think someone else had told me to use WinPCap under my SmartSniff... but I had forgotten.
Sure enough, added WinPCap (I'm on an XP, SP3 machine), and now I see something that either wasn't there before, or I was overlooking it. When I use the software supplied with my TEMPerLAN, I now see what I take to be the outbound transaction, the "Command BB 83" from my PC to the TEMPerLAN. More in a moment. I've always been able to see the part where the TEMPerLAN sends back the data. I'm not sure how I am supposed to tell which way stuff is flowing when I look at the SmartSniff screen... other than knowing by common sense, when, as now, I know what's in the messages. Is my guess at what is going on reasonable? It seems that the software in my PC generates a "thing" that it sends to the TEMPerLAN, well, to whatever is at the IP address I've given it, which, as it happens, is where the TEMPerLAN it. That "thing" then triggers the TEMPerLAN to do the same, but in reverse, and sending back to the IP address which came with the message from the PC. (I'm pretty sure that the TEMPerLAN, for this, is not using UDP. I even have an idea that I know what UDP is, you'll be glad to know!) A better statement, with proper terms, of what (may) be going on would be welcomed. SmartSniff has two lines now, as I said. The one that arises from the sending of Command BB 83 from PC to TEMPerLAN says... Protocol TCP Local addr: That of my PC (192.168.0.2) Local port: 3058 Remote addr: That of the TEMPerLAN (192.168.0.241 Remote port: 5200 The line from the messages back... differs just in the local port reported... Protocol TCP Local addr: That of my PC (192.168.0.2) Local port: 3057 Remote addr: That of the TEMPerLAN (192.168.0.241 Remote port: 5200 I can see the stuff I would expect when I look in the bottom pane of the SmartSniff... what a fantastic program!... window. Is there any other info which could help you help me? Thanks again!
