   Welcome to the confusing world of Hayes V-Series response codes. (OK, Hayes 
aren't the only perpetrators).
 
   First of all, 9600+ bps modems (and 2400s with V.42 or just MNP) are 
capable of talking to terminals at one speed while talking to another modem at 
another speed. In this case, your Hayes V-9600 has made a 2400 bps connect, 
but has decided to report CONNECT 9600 in order to keep the terminal program 
(which may be watching the number after the word "CONNECT") at 9600 bps. I'll 
bet that, if you look carefully and the software doesn't hide it, the CONNECT 
9600 is followed by a message like CARRIER 2400... that last bit tells you 
what the real conenct speed is but doesn't trip up software that isn't looking 
for the code word "CARRIER".
 
   DISCLAIMER: I've seen modems that do this; I have been told that the Hayes 
V-Series works similarly. I don't own a Hayes V-Anything. If you know better, 
feel free to correct me.
