[Duo2400] Re: USR 56k Sportster external modem problem

[Josh Keady]

Check the dipswitches on the rear of the thing.  The PC and Mac comm 
settings are different.  I THINK that's the only real difference 
between the two (besides the label.)  My 56k isn't here right now, but 
if someone else could post the dipswitch settings from the back of 
their working USR, that should do it.

Probably. ;-)
