What is the BBS using for detecting a caller? It could be looking for RING, or it could be looking at the state of DCD, or both. I have seen BBS software (like my own) that looks for RING, establishes the connection, and then looks at DCD to determine when the caller hangs up. If the DCD polarity is not programmable in the BBS software, you need to make sure the polarity is programmed correctly in the WiModem for your BBS software. So, what you could try is changing the DCD polarity. Normally, it is set to AT*D1. You could try AT*D0 and see if that works.
