var word network_packet_size = 0
No documentation found
var byte network_remote_mac[6]
MAC address of other end
var dword _network_remote_ip
IP address of other end
var byte network_remote_ip[4] at _network_remote_ip
No documentation found
var word network_var_offset = 0
variable offset for variables in the network_data
network_poll()
poll to see if there are any packets waiting for us
network_byte'put(word in variable,byte in value)
No documentation found
network_received_packet()
Reads a recieve packet. Verifies IP Header data such as IP address and checksum (with ip_header.jal), then sends the rest of the data to the correct procedure depending on packet type.
network_dword'put(word in variable, dword in value)
No documentation found
network_switch_dword_bytes(dword in out data)
switch byte order in a dword
network_set_remote_ip(byte in ip_0,byte in ip_1,byte in ip_2,byte in ip_3)
set remote ip address
network_word'put(word in variable, word in value)
No documentation found
network_word'get(word in variable) return word
No documentation found
network_checksum_16_byte_verify(word in start, word in size) return bit
Verify 16bit checksum from a byte array using every 2 bytes in the array. Mostly used for IP header checksums.
network_dword'get(word in variable) return dword
No documentation found
network_checksum_16_byte_calc(word in start, word in size) return word
Computes a 16bit checksum from a byte array using every 2 bytes in the array. Mostly used for IP header checksums.
network_byte'get(word in variable) return byte
functions to get/put variables into the network array
