That's what I thought. But somebody told me that you have to multiply by 8 to compute the *TRUE* overhead, including packet headers, retransmits, delays, timeouts, AND async overhead. So, the question is... What do we really want to know: How much of the 9600 baud line are we using? or How much of what is ACTUALLY available on the 9600 baud line are we using? taking into account the async overhead. Thanks for straighting this matter out. -- Dave Arnold dave@arnold.UUCP {cci632|uunet}!ccicpg!arnold!dave
