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. Gene Collins >This is getting to be a big problem! > >I have a new computer without a serial port.
