 Optionally the character used to split the input can be appended to every message sent out to the serial port.

+### Request
+
+Provides a connection to a request/response serial port.
+
+This node behaves as a tightly coupled combination of serial in and serial out nodes, with which it shares the configuration.
+
+Send the request message in `msg.payload` as you would do with a serial out node. The message will be forwarded to the serial port following a strict FIFO (First In, First Out) queue, waiting for a single response before transmitting the next request. Once a response is received (with the same logic of a serial in node), or after a timeout occurs, a message is produced on the output, with msg.payload containing the received response (or missing in case if timeout), msg.status containing relevant info, and all other fields preserved.
+
+For consistency with the serial in node, msg.port is also set to the name of the port selected.
