Ah ha! Thank you Angus and Piotr... Many "happy" tens of minutes spent "playing" with the excellent suggestions.
SmartSniffer.... Wonderful! Fascinating! Telnet... Ah yes, the "good old days"... I've burned hours with Telnet before, given my limited grasp of what I'm doing. (Last time it was with Dallas TINIs... faulty ones, at that!) I haven't tried Overbyte's Telnet... yet. Preferred to start with the bog standard one, see how I got on with that. ==== The rest of this rambles a bit... don't feel bad, Gentle Reader, if you decide to peruse no further! Smartsniffer, if I've understood things aright, shows that the vendor- supplied software talks to the device over 192.168.0.241, port 5200 Tried, under telnet, o 192.168.0.241 5200 .... also.... o 192.168.0.241 16000 .... and various variations using the other IP addresses in the config report. Telnet says "Connecting to 192.160.0.241..." ... but just sits there with that on the screen when I enter the first, and comes back quickly with "Could not open connection..." with the second. SmartSniffer doesn't "see" any interaction between 192.168.0.2 and 192.168.0.241 in either case. Suspending my anti-malware for a few minutes led to "interesting" results in SmartSniffer! By the way... yes... I have approached the manufacturer, too! They're "getting back to me". A clue? In the SmartSniffer report on the "conversation" being held between the device and my XP PC, the local address and port are 192.168.0.2 / 1506 192.168.0.2 *IS* the address I'd expect for the PC running SmartSniffer, and my Telnet attempts. Not sure if I need to do anything about the 1506? Do I somehow have to tell Telnet to watch for answers from ..241 to be directed to 1506? Is there a way? By the way... I do try to remember to shut down the vendor-supplied software when attempting a connection via Telnet. And thank you, all, for helping with a not-strictly-ICS matter... but I will use ICS (with Delphi 7, or maybe Lazarus) to write MY software for monitoring the TEMPerLAN... one day... I hope...
