5.2. Communications Garbled

If you are using the USB Serial Adapter to communicate 
between two computers over a serial cable, make sure that 
the communications settings are the same on each computer. 
For instance, if one computer is set up for 9600-baud, 8 data 
bits, no parity, one stop bit and hardware handshaking, errors 
can occur if the settings on the other device do not match.

5.3. Modem not detected/illegal operation in MODEM.CPL

It is possible that a modem attached to the USB Serial Adapter
will not be detected or a problem will occur in MODEM.CPL if
more than one USB hub is between the USB Serial Adapter 
and the root hub. This is a known problem in MODEM.CPL, 
a component of  Windows

®

98. The easiest solution to this 

problem is to attach the USB Serial Adapter to either the 
root hub (a USB port on the back of your PC) or to a hub 
that is connected to the root hub.
