Speakup and serial adapter cards

[acollins at icsmail.net]

Hello Curt!  This is Gene Collins.  Part of the problem for Speakup is
that each of the serial synthesizers are managed by a separate driver. 
They all use the standard irqs and addresses for ttyS0 and ttyS1.  I
think they even support ttys3 and ttys4.  Since pci serial ports get
assigned whatever irq and address is available at boot up, Speakup in
it's current form has no way to know where to look.  I think the same
situation holds true for usb serial ports.  So the question developers
need to answer is how to poll the system for the existence of any kind
of serial port, before polling the list of ports for a synth matching
the driver.

Just a suggestion for a starting place for developers to look at.
