FN_Open	procedure FN_Open(var fn_uri:PChar);overload; Opens connection to remote host at selected port using declared protocol. parameters: fn_uri - #FujiNet N: device connection string: N[x]:<PROTO>://<PATH>[:PORT]/ The N: Device spec can be found here: https://github.com/FujiNetWIFI/atariwifi/wiki/Using-the-N%3A-Device#the-n-devicespec
FN_Open	procedure FN_Open(var fn_uri:PChar; aux1, aux2: byte);overload; Opens connection to remote host at selected port using declared protocol. parameters: fn_uri - #FujiNet N: device connection string: N[x]:<PROTO>://<PATH>[:PORT]/ aux1 - additional param passed to DCB aux2 - additional param passed to DCB The N: Device spec can be found here: https://github.com/FujiNetWIFI/atariwifi/wiki/Using-the-N%3A-Device#the-n-devicespec
FN_WriteBuffer	procedure FN_WriteBuffer(buf: pointer; len: word); Writes (sends) data from memory to network device. parameters: buf - pointer to starting address of data len - data length (in bytes)
FN_ReadBuffer	procedure FN_ReadBuffer(buf: pointer;len: word); Reads (receives) data from network device. parameters: buf - pointer of buffer to store the incoming data len - data length (in bytes)
FN_ReadStatus	procedure FN_ReadStatus(status: pointer); Reads network device status and stores information in provided memory location. parameters: buf - pointer of buffer to store returned status information
FN_Close	procedure FN_Close; Closes network connection.
FN_Command	procedure FN_Command(cmd, dstats:byte;dbyt: word;aux1, aux2:byte; dbufa: word); Sends SIO command to #FN device parameters: cmd - DCB.DCMND byte dstats - DCB.STATS byte dbyt - DCB.DBYT word aux1 - DCB.DAUX1 byte aux2 - DCB.DAUX2 byte dbufa - DCB.DBUFA word
