Revision:
0:5150b09127e3
plays mostly music that you can do with notes length breakes and bind; Some already defined; Tool is to start a pump for water to give plant is too dry.; Meanwhie plays music the most part of all

helmut 0:5150b09127e3 36 *
helmut 0:5150b09127e3 37 * The first octet contains the packet type (top 3 bits), TCP
helmut 0:5150b09127e3 38 * 'push' bit, and flags that indicate which of the 4 TCP sequence
helmut 0:5150b09127e3 39 * numbers have changed (bottom 5 bits). The next octet is a
helmut 0:5150b09127e3 40 * conversation number that associates a saved IP/TCP header with
helmut 0:5150b09127e3 41 * the compressed packet. The next two octets are the TCP checksum
helmut 0:5150b09127e3 42 * from the original datagram. The next 0 to 15 octets are
helmut 0:5150b09127e3 43 * sequence number changes, one change per bit set in the header
helmut 0:5150b09127e3 44 * (there may be no changes and there are two special cases where
helmut 0:5150b09127e3 45 * the receiver implicitly knows what changed -- see below).
helmut 0:5150b09127e3 46 *
helmut 0:5150b09127e3 47 * There are 5 numbers which can change (they are always inserted
helmut 0:5150b09127e3 48 * in the following order): TCP urgent pointer, window,
helmut 0:5150b09127e3 49 * acknowlegement, sequence number and IP ID. (The urgent pointer
helmut 0:5150b09127e3 50 * is different from the others in that its value is sent, not the
helmut 0:5150b09127e3 51 * change in value.) Since typical use of SLIP links is biased
helmut 0:5150b09127e3 52 * toward small packets (see comments on MTU/MSS below), changes
helmut 0:5150b09127e3 53 * use a variable length coding with one octet for numbers in the
helmut 0:5150b09127e3 54 * range 1 - 255 and 3 octets (0, MSB, LSB) for numbers in the
helmut 0:5150b09127e3 55 * range 256 - 65535 or 0. (If the change in sequence number or
helmut 0:5150b09127e3 56 * ack is more than 65535, an uncompressed packet is sent.)
