    I have a Practical Peripherals internal 2400 baud MNP
    modem which I bought recently.

    At 1200 baud it works great; I have accessed boards all
    over the country with no difficulty.  

    But at 2400 baud I get lots of noise.  The noise seems
    to be on the receiving end, i.e., I see lots of noise
    characters on stuff that's echoed to me but the boards
    on the other end seem to get everything I send OK.  I've
    tried several different boards and have always had the
    same problem but I've had no problems at 1200 baud.  
                           
    I know that noise is a bigger problem at 2400 baud than
    at 1200 baud but how do I tell if there is something 
    more seriously wrong with the modem?   

    None of the boards I accessed are "local" they are all
    in at least another area-code if not in another state.
    The only BBS's that I know of in my area code (508) 
    are actually farther away than the ones in other area
    codes (like 603 or 617), so I'm sure there is a certain
    amount of noise, but I don't know what's reasonable.  
    I bought a 2400 baud modem to reduce long-distance charges!

    Thanks in advance.                      ---Peter
