It doesn't exist (in the new form) yet.  Right now, it allocates and 
talks to a hardwired serial port.  I want to change it so I connect to a 
PC running a terminal emulator on the net.  Easiest way is to do
TELNET> CREATE_SESSION, which connects to the PC running vaporware, and 
the code talks to the resulting TNAxxx: device.

Yes.  Someone (I think it was you) suggested that, and it is probably 
what I will wind up doing.  Thanks.
