EthCmd.wValue      = htons((WORD)offset); 

EthCmd.wIndex      = htons((WORD)outch); 

EthCmd.wLength     = 0; 

To receive data from the host port set the packet as follows. After sending the packet the programmer will 
receive 1 byte, which is the value the Ethernet port read from the Turbo PMAC’s CPU host port. 

EthCmd.RequestType = VR_UPLOAD; 

EthCmd.Request     = VR_PMAC_PORT; 

EthCmd.wValue      = htons(offset); 

EthCmd.wIndex      = 0; 

EthCmd.wLength     = 0; 

VR_PMAC_READREADY 

This packet permits determining if there is data on the Turbo PMAC CPU ready to be read. 

Two bytes will be returned.  The first byte, if non-zero, indicates there is data to be read; if zero, there is 
no data to be read.  The packet will be set up as follows: 

EthCmd.RequestType = VR_UPLOAD; 

EthCmd.Request     = VR_PMAC_READREADY; 

EthCmd.wValue      = 0; 

EthCmd.wIndex      = 0; 

EthCmd.wLength     = htons(2); 

ETHERNETCMD EthCmd; 

char        data[2]; 

int         rc; 

EthCmd.RequestType = VR_UPLOAD; 

EthCmd.Request     = VR_PMAC_READREADY; 

EthCmd.wValue      = 0; 

EthCmd.wIndex      = 0; 

EthCmd.wLength     = htons(2); 

rc = send(sock,((char *)&EthCmd),ETHERNETCMDSIZE,0); 

rc = recv(*((SOCKET *)vh[dwDevice].hDriver),data,2,0); 

return data[0]; 

VR_CTRL_REPONSE 

This packet permits obtaining the response after sending a control character.  The packet is set up as 
follows.  The received data is the response to the sent control character.  Meaningful data is returned for 
the following control characters <CTRL-B>, <CTRL-C>, <CTRL-F>, <CTRL-G>, <CTRL-P>, and 
<CTRL-V>.  All other data control characters do not return meaningful data. 

EthCmd.RequestType = VR_UPLOAD; 

EthCmd.Request     = VR_CTRL_RESPONSE; 

EthCmd.wValue   = htons(outchar);//outchar=ctrl char to send out 

EthCmd.wIndex   = 0; 

EthCmd.wLength  = htons(len); 

rc = send(sock,((char *)&EthCmd),ETHERNETCMDSIZE,0); 

rc = recv(sock,outstr,len,0);  // returned data appears  

VR_PMAC_WRITEBUFFER 

This packet permits writing multiple lines to the Turbo PMAC with just one packet.  The packet is set up 
as follows.  The received data is the response to the sent control character.  It is usually used for 
downloading a file.  Data should be of the form in which each line is separated by null byte.
