I have the Siamese 2.5 software, but I've lost my 4 page instruction manual :-(
I've never bothered connecting it via an ethernet connection, but I still use it via a serial cable to share my Amiga and PC drives... and it works very well.
I have also got the RTG function working too. I was really impressed to retarget my humble AGA A1200 and ECS A3000 to a full 16 bit 1024x768 display via my PC even over a slow serial link.
If all else fails and I'm not going to be sued by Hi-Soft then perhaps I can help with the software. Meanwhile, if anyone can scan and email me the paper manual then I'd appreciate it :-)
PS. NewIcons will cause OS3.1 and lower to hang unless you remove the DefIcon command from the startup sequence. I haven't had this problem with OS3.5 and I haven't tested it with OS3.9 as I refuse to by anything from those H&P crooks until they start paying Amiga Inc their fees.
