There are two solutions.
You can get a PCMCIA serial card - the Socket Communications cards are
reported to work, and sell for aorund $100 I believe, but I may be
off. OF course they take a PCMCIA slot. I don't think the two port cards
work.
The other option is related to the fact that your Newton already has two
serial ports. It has an internal modem connector that is for another
serial port. Also, the Interconnect port has the same pins wired to it.
FOr this to work, you need more hardware. There's some circuitry needed
for this to function. Basically serial driver chips are needed. For the
electronically skilled, the design is pretty easy. Making one is more
challenging of course...
Also, some software side work is needed to get software to use that port,
but it's pretty easy; I managed to convince Newton Internet Enabler to use
the other port by manually changing configurations...
Hope this helps a bit.
