Re: dosgate/dosemu.

Hello!

I know nothing about DoubleTalk PC, but to get it running under dosemu you have
to get it running under dos.

As far as I can tell, any hardware for speech synthesis or braille display
comes with some sort of dos screen reader: you just have to get it running in a
dos boot floppy with a batch file named 'reader.bat' that makes it start.

This should be enough with many serial devices; in this case we are having a
hardware card, if I understand what the DoubleTalk is.  To make it work under
dosemu, you have to tell in dosemu configuration what hardware ports and
interrupts it should give access to dos programs.

You give access to interrupts with the $_irqpassing directive, setting it to a
space-separated list of interrupt numbers, as in:

	$_irqpassing = "1 4 6"

You give access to ports with the $_ports directive, setting it to a
space-separated list of ports and/or port ranges, as in:
	
	$_ports = "0x378 0x3e8 range 0x220,0x230"

A port range is indicated by the 'range' keyword followed by the two
comma-separated extremes of the range.

To know what hardware ports and interrupts your DoubleTalk is using, since I
guess you have it running under Linux, you can issue these commands:

	cat /proc/ioports
	cat /proc/interrupts

They list the io ports and interrupts currently in use by the kernel device
drivers, and you can look for what's used by the DoubleTalk driver.

As a personal note, I have to say that while trying to run Linux-supported
devices with dosgate is good for testing dosgate (and I thank you very much for
willing to do it), it's always best to take advantage of the native Linux
support one could have for its hardware.


Thank you for your interest! Enrico
