Terminal Information CFR API GetDCTInfo

7526 Ethernet Flash level 4.24 and higher or base EPROM 3.12 or higher includes a new CFR API which allows the CFR programmer to have access to

• The 7526's IP address (blank for non-Enet 7526)
• The DCC server's IP address with whom the 7526 is talking (blank for non-Enet)
• The 7526's physical Ethernet MAC address (MSB form; not initialized for non-Enet).
• The number of buffered transactions stored in the 7526
• The number of bytes of the transaction buffer which are available for holding more transactions
• Whether the DCC server is accepting transactions right now (always 0 for non-Enet)

7526 CFR toolkit files (CFRAPI26.H, CFRAPI26.LIB) dated 5/28/97 are required to build CFRs with this function.

Example:

/* Returns E_INTERNAL if run on a 7526 with EPROM older than 3.12 (non-Enet)    */
/* or FLASH-ware older than B4.24.                                              */
/* (sprintf_752x is from the sample CFR26LIB.LIB library)                       */
