AH
ES:DI
0x45 (= PPPCLIENT_SET_OPTIONS)
Pointer to an array of PPP_Option data structures. This array is terminated by first PPP_Option structure
with a null optionValuePtr member (see example below).
Return Value
Comments
AX = -3 PPP Connection already established AX = -2 PPP client is not installed.
AX = -1 Invalid Option(s) AX = 0 Success
If you want to use this function, you have to call it before opening a connection (see related links below).
Settings options during an established connection will not work!
The settings are only valid for the next established connection. The data structures referenced here with
ES:DI must persist until after the subsequent PPP client open function completes.
A C-Library function is available in the CLIB file TCPIP.C. Here is an example which sets three PPP options
using the C-Library wrapper functions:
// Allow remote peer to set primary DNS IP.
unsigned long DNS_Pri_IP = 0L;
// Allow remote peer to set secondary DNS IP.
unsigned long DNS_Sec_IP = 0L;
// Allow remote peer to use VJ TCPIP header compression.
unsigned int ipcp_comp = 1;
PPP_Option My_Options[] = {
{ PPP_IPCP_PROTOCOL, PPP_OPTION_ALLOW, PPP_IPCP_COMP_PROTOCOL,
(const char *)&ipcp_comp, sizeof(ipcp_comp)},
{ PPP_IPCP_PROTOCOL, PPP_OPTION_WANT, PPP_IPCP_DNS_PRI,
(const char *)&DNS_Pri_IP, sizeof(DNS_Pri_IP)},
{ PPP_IPCP_PROTOCOL, PPP_OPTION_WANT, PPP_IPCP_DNS_SEC,
(const char *)&DNS_Sec_IP, sizeof(DNS_Sec_IP)},
// This last PPP_Option is used to terminate array.
{ 0, 0, 0, NULL, 0}
} ;
//***** Call the C-Library functions as follows ****
// Install options with CLIB function
PPP_Client_SetOptions(&My_Options[0]); // Point to first member of array
PPP_Client_Open(&pppclient); // Open the connection
