Hi all. Perhaps this would be better suited for the Emacspeak list, but I figured I'd ask it anyway just because this could have to do with Speakup, not sure. When I go to run tcl to make sure the dtk-exp speech server is working properly, I get the following: Could not open /dev/ttys0: i/o error. I did an export DTK_PROGRAM=dtk-exp and an export DTK_PORT=/dev/ttys0 as instructed in the Makefile. I also killed Speakup before executing tcl /usr/local/emacspeak-15.0/servers/dtk-exp, and I still got an i/o error when accessing /dev/ttyS0. Any ideas on how to fix this? Thanks!
