Apollo II and kernel 4.18.x

[Dietmar Segbert]

Hello,

i am using buster/sid with kernel 4.18.x and espeak.

I have also tested to use my old apollo ii connected with an usb-to- 
serial-adapter with a ftdi-chip.

modprobe speakup-apollo dev:/dev/ttyUSB0

load the modul, but the synthesizer will not speak.

If i cat a string to /dev/ttyUSB0 the apollo II will speak.

The volume ist not "0" and in

sys/accessibility/speakup/synth


i found "apollo".

What can i do? Thanks for your help.

Regards

Dietmar Segbert
