I am writing an application which needs to communicate with an external device
(a network bridge, actually) through the modem or printer ports. I have two
questions :

0) Can anyone direct me to some sample code which uses the RAM serial driver to
read and write bytes to/from either port? In fact, is the RAM serial driver the
best way to do something like this (what are the options / pros / cons)?

1) Is it a safe or sanctioned operation to use nullEvent to read any received
data from the serial port? What I need to do is allow event processing to
continue while I am waiting for replies. Something that might simplify this is
that there are no unsolicited responses, so I know when to look for received
data : only after I've sent some out. But while I am waiting for a reply packet,
I want to continue to respond to user input.
