Hi. I have apollo II synthetiser. I would like to connect it to
speakup, but i have computers without physical serial port. Usb to
serial interfaces don't work with speakup of course. Is it possible to
connect speakup to apollo. I've heard about possibility to connect
external synthetiser to speakup using express card to com adapter, but
my computer doesn't have physical express card port, so i must again
use express card to usb converter.
Thank you for help.
Lukasz.

Hi,
I thought that it will work with a USB to serial adapter, but you may not
get the initial computer boot-up messages because the USB to serial driver
would not have been loaded yet.

No, speakup and the Apollo, or any other hardware speech-synthesiser
will not work with a USB to serial adaptor.
I believe this to be because a genuine serial port (RS232) and speakup
use the hardware hand-shaking pins (RTS and CTS?), to communicate
readiness to send and recieve data. The USB to serial adaptors will
either not support this hardware hand-shaking or it takes a differently
written program to use it.

I have only used a USB to serial in Windows.
But I thought that others had done it after the computer had gone through
its initial screens.

It has nothing to do with when or whether the computer loads the driver
for the USB to serial adaptor. It just doesn't support the
hardware-handshaking that speakup and the hardware synth need.
You might hear the effect that for the first few seconds it seems to
work but then goes silent. I assume this is because speakup is waiting
for the hand-shake from the synth that indicates it has finished the
last chunk and is ready for more.
I had email once before about this privately from someone trying to use
a USB to serial adaptor and I recommended he install an RS232 serial
port card and that fixed his issues.

I use a hardware synth all the time with USB to serial converters, but
they have to use the ftdi chip set. The only problem is that it does
buffer more than I would like.
