The echo server returns any message that it receives to the sender. It is a confidence testing service for the LAM network.
The message length must not exceed the maximum network message length MAXNMSGLEN, defined in <net.h> and factory set to 8192 bytes.
Upon successful completion, the number of bytes echoed is returned. If an error occurred, −1 is returned and the global variable errno is set to indicate the error.
