Anyone know if it is possible to serially link two pcs together one of which
has an internet connection, then get masquerading going and get the internet
on the serially-linked box?

Yep.  Read the IP Masquerade HOWTO

No problems!

You can link the 2 machines with a ppp link.
Here's a practical example: (assuming machine A is connected to machine B
which is running IP masquarade)
1- Connect the serial ports of the two machibes with a null modem cable.
2- On both machines (if using COM2): setserial /dev/ttyS1 spd_vhi
3- On machine A: pppd -detach lock crtscts defaultroute
192.168.2.1:192.168.2.2 /dev/ttyS1 38400 &
4- On machine B: pppd -deatach lock crtscts passive silent  /dev/ttyS1 38400
&

Machine A will be 192.168.2.1 and machine B will be 192.168.2.2 and the
default
gateway for machine A will be 192.168.2.2. All you have to do next is to set
up
your masquerading stuff properly.

That's it your in business!
