       Subject: Info on MicroExplorer 

       I'm also interested if anyone has a patch to allow the uExp to use more
       than one serial port on the Mac II.

   >From a quick look at the source, it appears that on a microExplorer you
   can specify an extra keyword to SYS:MAKE-SERIAL-STREAM, :PORT, which can
   be either :A or :B for the two ports.  I don't actually have access to a
   microExplorer, so I can't guarantee that it works.  The relevant file is
   sys:serial;mx-serial-stream.lisp.

Thanks for the lead, Paul. Alas, after making a stream for port a, upon trying
to make one for port b I get a "couldn't rd/wr/ctl/sts cause driver not
opened", TB:SIGNAL-USERR <- TB:!CONTROL <- TB:!SERRESET.

SO I guess there needs to be a driver which TI never got around to making.
Perhaps it's a toolbox hack that needs to be set up. I dunno.
