I'll just keep schlepping cables around the room, I guess, at least for now. -- Ian ----- Reply: ----- The bare TTL RS232<>BT devices start at < $5.00 e.g. eBay 200924726178 True RS-232 < $15: e.g. 400706121660 I've used both with no issues. For RS-232<>Ethernet I prefer a used Lantronix UDS-10 or equivalent; more professional configuration options/software than the current Chinese stuff. You used to be able to pick them up for around $20 if you kept your eyes open. e.g.: 131252594914 271574124592 Or maybe: 191248187972 No problem putting pretty well anything with a serial port up on the Internet; the Lantronix devices are pretty flexible but not all other devices handle handshaking properly and buffer overflow can be a problem. I've logged into a CP/M system in Australia with a Tandy M100 laptop in Toronto ;-) And then there are the RS232<>WiFi adapters... m
