217 | UDP Server Receive Lock | 0 – 255 | 0 | 0.1s | |

When this register is set to 0 (the default), the receive lock is disabled. The modem will only accept packets from the calling client’s IP and port until the session is closed. Packets from other callers are dropped. See Section 6.2.1.2 for a full discussion.
If the value is
The modem will queue client packets, expecting the local host to respond to each client in turn. As each response is sent, or the timer expires, the next client’s packets are delivered to the local host, up to a packet from yet another new caller. A new lock is set and the timer restarts.
Packets are delivered in the order they are received. If more than one packet arrives from a given client, those packets that arrive without intervening ones from another source will be delivered the host as a set. Only one response is needed to clear the lock and allow the next client’s packet(s) through.
If packets arrive from the currently active client while the local host has not replied, and the modem has not received packets from other clients, they will be delivered to the local host immediately. Buffering of packets begins with the first packet from a client other than the active one. From that point all packets from any client are held back (buffered) pending release of the lock.
