Hi All, I am a long time lurker, first-time poster. I have done my best to search the following question but apologise if I missed the glaringly obvious topic that addresses this question. I am currently experimenting with LUA through a SHAC (and PACA) to see if I can port over some of my more complex automation tasks across IP connected devices but am struggling to find example/documentation. Most of these devices are running simple TCP socket-based IP bridges to their existing RS-232 control interfaces. Would someone have easy access to a LUA sockets primer of sorts or a simple sample TCP socket application in LUA that includes a 3-way handshake followed by a command and response? eg (for a JVC projector): Open Connection to IPORT (TCP) Wait for "PJ_OK" (up to 5s) Reply with "PJREQ" Wait for "PJACK" (up to 5s) Send Command (typically Hex, eg; \x 06 89 01 50 57 0A) Wait for Response (typically Hex, eg; \x 40 89 01 50 57 RR 0A) Close Connection Any support would be appreciated. Kind Regards
JVC in this case. But the approach is broadly the same for similar for similar IP bridged RS232 based controls. I have had some success with a Denon AVR despite the less than optimal lua documentation but have not tackled how to send hex-encoded strings.
