[net.micro] FW & Epson FX user-defined characters

I wrote to Mark of the Unicorn re my problem getting the Final Word to use
the user-defined character set on an Epson FX-80.  A few days later, I
received a call from MoU with the solution.

The problem was that the Epson requires control strings including ASCII
NULs to switch between the two character sets.  The FW Config program
treats NUL as an end-of-string marker.  The solution is to get some key on
your keyboard to generate the code 80H (hex).  Then, define the Printer Out
port to be 7 bits.  Enter 80H in the printer control strings where a NUL is
expected.  Config accepts the 80H and when it gets transmitted to the
printer, the 8th bit is removed so the printer receives NUL.
