From: Russell Nelson <nelson@crynwr.com> To: mgetty@muc.de Subject: Problem with call_program I defined R_CALL_PROGRAM in voclib.h, which causes the voice mode code to execute vg_call. Problem is that the shell script expects to be able to use stdin/stdout to talk to the tty, but the process that owns the lock file is now gone. So it gives up soon after answering.
