Re: [orca-list] DoubleTalk on USB

I wonder what sound system would drive a hardware synth.  Is the Pulse audio
versus Alsa issue even a concern if one has an external synthesizer?

Well, you have two problems. The first is not all USB to serial 
adapters will work with your Doubletalk. I tried this option with a 
number of hardware synths and discovered that some USB to serial 
adapters work, and others don't for some reason.

The reason, according to discussions on another mailing list, is that 
some USB to serial adapters don't implement all of the serial lines, 
in particular the hardware flow control required by some devices.

its also worth noting that speakup doesn't work with USB to serial adaptors.
Speakup so far as I know can only work with onboard serial ports that use
the traditional legacy ports, 3F8H etc.
