Ok I've had part success in that if I change
if (class->pseudofd > -1) {
/* Pause some amount of time */
res = read(class->pseudofd, buf, sizeof(buf));
to
if (class->pseudofd > -1) {
/* Pause some amount of time */
usleep(1);
res = read(class->pseudofd, buf, sizeof(buf));
At least asterisk responds at the cli now. I think on a 2 processor machine
the above read took no time at all. What kind of delay should there be?
However even though asterisk now starts up cleanly and can register external
resouces. It does not respond to any connections sip/zap dialin etc. Looks
like the select routine is being blocked somehow. Who wrote the FreeBSD MOH
routines?
