For the ZyXEL modems, the modem could be configured with several megabytes of 
RAM to store incoming faxes and drive a printer via the parallel port 
allowing the modem to act as a standalone fax receiver.  Otherwise, there was 
a supposed advantage in speed compared to a serial port.  Given the common 
availability of 115K2 and higher speed buffered serial ports, the speed 
advantage of the parallel port devices never materialized.  Either the serial 
or parallel interfaces ended up spending time waiting for the modem to be 
ready for the next character.
