[racket-users] Issue about tcp port, server doesn't receive bytes using read-bytes-avail!* and client using write-bytes

I am writing a tcp server program. Server uses non-blocking reading and client uses write-bytes, then server never read any bytes and write-bytes returns the right value. But when I change client's write-bytes to write-bytes-avail, server receives bytes immediately. I don't know why this happens
