IPC@CHIP Documentation - SC12 @CHIP-RTOS V1.10

DS:SI
CX
6 Get pointer to AtEntry data structure (only of the internal Ethernet device interface)
7 Get array of far pointers to IfMib entries of all current open TCP/IP device interfaces.
(Local Loopback, Ethernet, PPP server, PPP client)
8 Get far pointer to unsigned long sysuptime variable (10 Hz counter).
If parameter AL==7, ES:DI must contain the address of a buffer into which up to CX far pointers to IpMib data
structures can be reported by this API.
If parameter AL==7, CX specifies the number of far pointers (capacity) which the user buffer at [DS:SI] can
hold.
Return Value

DX != 0 AX != 0 : @CHIP-RTOS without internal SNMP MIB variables
DX = AX = 0 ES:DI contains a pointer to the structure unless input parameter AH was 7,
in which case the user provided array (still addressed by DS:SI) contains the far pointers to the
IfMibentries of the currently installed device interfaces. CX is set to indicate the total number of
currently installed devices. If CX is less than it was on entry, then the reported list of pointers is not
complete due to lack of user buffer space.
If this API call is used with AL==1-6, or 8, the pointers are granting direct access to the internal TCP/IP stack
counters. It's recommended to execute these calls only one time at the start of your application.
For AL=7, the API call returns the pointers to the interface variables for the currently installed device
interfaces. To maintain an up to date array of pointers for all currently opened device interfaces, it is
necessary to periodically request (e.g. every 10 seconds) the array of pointers.
Note: These structures are only available in @CHIP-RTOS versions which contain the SNMP option.
A SNMP agent is not part of the @CHIP-RTOS. But if a user is able to implement an agent based on
the TCP/IP API, they need access to the internal TCP/IP SNMP variables. The SNMP MIB variables are
not a part of our current official 6 @CHIP-RTOS versions. It is necessary to order directly a @CHIP-
RTOS version which includes this feature.
Interrupt 0xAC service 0x65: API_FTP_GET_LOGIN, Get FTP server login counters
Parameters
AH
Accesses the FTP server login counters.
0x65 (= API_FTP_GET_LOGIN)
Return Value
DX != 0 AX != 0 : @CHIP-RTOS doesn't support FTP server
DX = AX = 0
ES:DI contains the address of the 32 Bit (unsigned long) login counter
DS:SI contains the address of the 32 Bit (unsigned long) login fail counter
