Hi Amy, Copying this to the list since I'm sure someone else can answer this better than I! I'm not sure about the 'a' and 'c' suffixes, but according to the intro man page (man 4 intro) the r and non-r bit is for unbuffered (i.e. raw, hence the r) and buffered devices specifically. The man page goes into more detail -- you should read that through :). -- Greg Lewis glewis@trc.adelaide.edu.au Computing Officer +61 8 8303 5083 Teletraffic Research Centre To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
