+ * Compressed packet format:

+ * The first octet contains the packet type (top 3 bits), TCP

+ * numbers have changed (bottom 5 bits). The next octet is a
+ * conversation number that associates a saved IP/TCP header with
+ * the compressed packet. The next two octets are the TCP checksum
+ * from the original datagram. The next 0 to 15 octets are
+ * sequence number changes, one change per bit set in the header
+ * (there may be no changes and there are two special cases where
+ * the receiver implicitly knows what changed -- see below).
+ *
+ * There are 5 numbers which can change (they are always inserted
+ * in the following order): TCP urgent pointer, window,
+ * acknowlegement, sequence number and IP ID. (The urgent pointer
+ * is different from the others in that its value is sent, not the
+ * change in value.) Since typical use of SLIP links is biased
+ * toward small packets (see comments on MTU/MSS below), changes
+ * use a variable length coding with one octet for numbers in the
+ * range 1 - 255 and 3 octets (0, MSB, LSB) for numbers in the
+ * range 256 - 65535 or 0. (If the change in sequence number or

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