It is sent on boot and on MANUAL reset of the port. NOT after each call.

This argument is moot as the data it was based on is incorrect.

The correct string for a USR, from the manaul, is AT&F1s0=1&W

s0=1 is omitted if dip switch 5 is set. I've already requested that we
add it to the string we ship.
