Unfortunately, many others don't support multiplexing at all, are buggy (esp. WRT flow control), don't support channel attribute discovery, are incapable of being switched out of multiplex mode without power cycling, and/or don't supply documentation for their particular implementation of the supposedly-standardized multiplex mode without signing a too-restrictive NDA. -- Matthias Urlichs | {M:U} IT Design @ m-u-it.de | smurf@xxxxxxxxxxxxxx Disclaimer: The quote was selected randomly.
