emptied. If this option is disabled, SE5001 will keep old serial data when the connection is broken (Figure 3.16).
3.2.12. Setting Packet Delimiter
Packet delimiter is a way of packaging serial data. It can prevent serial data from being truncated by packing them
in the same Ethernet packet. SE5001 provides two kinds of packet delimiter: Timer and Character. The default
timer is 2 ms (0ms to disable this function). This means that if SE5001 does not receive new serial data within 2ms,
it will send out all the serial data in buffer in one packet over Ethernet. The way to change the delimiter timer is
shown in the following figure (Figure 3.17):

Another kind is character delimiter. If the character delimiter is set to 0x0d, this means SE5001 will send out all the
serial data in buffer in one packet over Ethernet only if it reads 0x0d. The following figure shows how to configure
character delimiter:
