Greg, Did you receive this test email? I wrote a reply to your email to me / the list and it bounced from the list and I wasn't sure why, I wrote the list admin but it said he is on vacation in the uk. :) I signed up with my work address so I can still post, but anyway, to say the least a bit of an adventure. :)
Let me know if you get this at least, and as well I am copying the list as a test email. I am guessing it won't get through. For some reason it seems to be labeling me as spam?? thanks again Nick "All unix, all the time." http://npt.ath.cx Greg KH wrote: > On Wed, Dec 27, 2006 at 01:38:52PM -0600, nick thompson wrote: > >> Hi, >> Basically, in a nutshell, if I cat a text file to /dev/ttyS0, and have >> a null modem setup going to /dev/ttyUSB0 (the pl2303x) the first time I >> cat it, it goes through fine.
