31 * Fixed potential race in omninet_write_bulk_callback
32 *
33 * (07/19/2000) gkh
34 * Added module_init and module_exit functions to handle the fact that this

118 * The omni.net always exchange 64 bytes of data with the host. The first

120 *
121 * oh_seq is a sequence number. Don't know if/how it's used.
122 * oh_len is the length of the data bytes in the packet.
123 * oh_xxx Bit-mapped, related to handshaking and status info.
124 * I normally set it to 0x03 in trasmitted frames.
125 * 7: Active when the TA is in a CONNECTed state.
126 * 6: unknown
127 * 5: handshaking, unknown
128 * 4: handshaking, unknown
129 * 3: unknown, usually 0
130 * 2: unknown, usually 0
131 * 1: handshaking, unknown, usually set to 1 in trasmitted frames
132 * 0: handshaking, unknown, usually set to 1 in trasmitted frames
133 * oh_pad Probably a pad byte.
134 *
135 * After the header you will find data bytes if oh_len was greater than zero.
