+ * udpecho expects the following format: udpecho:bind_addr:listen_port[:sendto_port:datasize]
+ * bind_addr: IP address to bind to
+ * listen_port: port number on which the udpecho listens
+ * sendto_port [OPTIONAL]: port number to echo datagrams to (echo to originating IP address)
+ * datasize [OPTIONAL]: max size of the data red from the socket in one go
+ *
+ * REMARK: once an optional parameter is given, all optional parameters need a value!
+ *
+ * f.e.: ./build/test/picoapp.elf --vde pic0:/tmp/pic0.ctl:10.40.0.3:255.255.255.0: -a udpecho:10.40.0.3:6667:6667:1400
