flags | Notification to the API that the associated field has been used. |
link_name | Name of the X.25 port used for an incoming call.
Note: This is set to null on received packets. |
called_addr | Pointer to the network user address (NUA) of the called data terminal equipment (DTE). The address is given in ASCIIZ format. |
calling_addr | Pointer to the NUA of the calling DTE. The address is given in ASCIIZ format. |
cb_fac | Pointer to the facilities information in the cb_fac_struct structure. |
user_data_len | Field length for call user data (CUD). |
user_data | Pointer to call user data (CUD). |
