I'm also on the heyu list, where a couple of years ago we became aware that 99% of the adapter problems heyu was having (and coincidentally the apcupsd list found the same) were related to the user using a PL2303 based adapter. So we started telling the newbies to bin them and get FTDI stuff, because it Just Works(TM). And it does, there are 5 or 6 of them in this system right now, and they are dependable and 100% transparent.
2 of the ones I am using are booster hubs on the other end of 16 foot cables. Nary a hiccup in a years use. Mother nature blew one of them all to hell, but when the systems are 25 feet apart, the EMP from a nearby strike can do heavy duty things to electronics. >Suggest looking at something from SiLabs. > >> Date: Wed, 8 Apr 2009 17:32:08 -0400 >> From: d...@delorie.com >> To: geda-user@moria.seul.org >> CC: mrumun...@popdial.com >> Subject: Re: gEDA-user: FT232R >> >> >> Ah, the perils of open source.
