Sigh - IMO 1.5M is an insane idea for that and so needless. > None of my other serial adapters could do the speed necessary. I just retried with the CH340 - again no success, but noticed that the chip on my adapter is unlabeled. So probably it isn't a genuine. I should have some others, but not at home, and I also have some loose CH340G chips. -- B.Walter http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm.
