Make certain both ends of the connection are expecting the same type of 
handshaking, either hardware or software.  The cable may also be 
suspect, because requirements vary for how DTR/DSR and other signals are 
wired.  The simplest is software handshaking and a three or four-wire 
cable.  That cable might still need pins tied together on one or both 
ends, depending.
