APPENDIX A: SNAP ETHERNET-BASED BRAIN MEMORY MAP PPP Configuration—Read/Write (Does not apply to SNAP Simple I/O) Use this area to configure PPP if you are communicating with the brain via a modem connection. For more information on setting up PPP, see the ioManager User’s Guide. Starting Address Length Type Description FFFF F03E 0000 4 IP Local IP address for PPP interface. Default is 192.168.0.1 FFFF F03E 0004 4 IP Remote IP address. This IP address is assigned to devices that connect to the brain and request an IP address. This address must be on the same subnet as the Local IP address. Default is 192.168.0.2 FFFF F03E 0008 4 UI Serial port speed. Default is 19,200 bps. FFFF F03E 000C 4 UI Serial port parity. Default is none. None = 0x10; even = 0x4; odd = 0x0 FFFF F03E 0010 4 UI Serial port stop bits. Possible values:1 or 2. Default is 1. FFFF F03E 0014 4 UI Serial port data bits. Possible values: 6–8. Default is 8. FFFF F03E 0018 40 S-ZT Modem initialization string (null terminated). This string is sent to the modem once when the brain boots. The modem must be configured to ignore DTR and use no flow control. The modem is reset (ATZ) between each call. We suggest that settings be saved to a profile in the modem’s NVRAM and the modem configured to load that profile every time it is reset. The modem initialization string can be used to perform this task whenever the brain powers up. See the brain user’s guide for more information. Default is: AT&D0^M~~~~ FFFF F03E 0058 4 IP Subnet mask for Local IP address. Default is 0.0.0.0—Required only if you are using classless IP addressing. If not, leave it at 0 and the brain will calculate the appropriate subnet from the Local IP address. FFFF F03E 005C 4 UI Maximum number of times PPP will retry to authenticate a link. Default is 3. FFFF F03E 0060 4 UI Serial port flow control. 0 = none; 1 = hardware (RTS/CTS) FFFF F03E 0064 40 S-ZT Modem hangup string. This string is sent by the brain to the modem when the brain wants the modem to hang up. (Note: A ^t in this string forces an LCP terminate request packet in a PPP frame to be sent, which can be useful to force packet-switched data devices with a local PPP interface to hang up and enter command mode.) Default is: ~~~+++~~~ATH0^M~~~ Last valid address for this section: FFFF F03E 00A3 FFFF F03E 6000 4 UI Enable PPP for incoming calls. Default is 0. Enable = 1, Disable = 0 116 SNAP Ethernet-Based I/O Units Protocols and Programming Guide
Starting Address Length Type Description FFFF F03E 6004 4 UI Set default gateway to PPP interface. Default is 0. Yes = 1, No = 0. If enabled, all IP packets addressed to destinations that are not on the same subnet as the Ethernet interface will be sent out the PPP interface. Enable this only when the remote device can route packets to their ultimate destination. The setting is in effect only when an incoming PPP session is active. FFFF F03E 600C 40 S-ZT Modem listen string (null terminated). Default is: ATS0=1^M~” Prior to waiting for a call, the brain resets the modem and sends this string to it. The string is sent every time the brain prepares to listen for a call. FFFF F03E 604C 4 UI Inactivity timeout. Number of seconds an incoming link can remain idle before the link is closed. Default is 30. FFFF F03E 6050 10 S-ZT Login (null terminated). Login name for authentication on incoming PPP sessions. FFFF F03E 6060 10 S-ZT Password (null terminated). Password for authentication on incoming PPP sessions. Last valid address for this section: FFFF F03E 606F FFFF F03E B000 4 UI Enable PPP for outgoing calls (dial on demand). Enable = 1; disable = 0. Default is 0. FFFF F03E B004 4 UI Specify local IP address. Yes = 1; No = 0. Default is 0. For outgoing calls, the brain can either specify the IP address it wants to use (entered in FFFF F03E 0000) or ask the remote device to assign an address. FFFF F03E B008 4 UI Set default gateway to PPP interface. Yes = 1; No = 0. Default is 0. If enabled, all IP packets addressed to destinations that are not on the same subnet as the Ethernet interface will be sent out the PPP interface. Enable this only when the remote device can route packets to their ultimate destination. The setting is in effect only when an outgoing PPP session is active. FFFF F03E B00C 4 -- Reserved FFFF F03E B010 10 S-ZT Login (null terminated). Login name for authentication on outgoing PPP sessions. FFFF F03E B020 10 S-ZT Password (null terminated). Password for authentication on outgoing PPP sessions. FFFF F03E B030 4 PPP inactivity timeout in seconds. Default is 30. If the brain sends no traps for this number of seconds after the PPP session is negotiated, the modem will hang up. A zero in this field disables the timer. FFFF F03E B034 40 S-ZT Phone number to dial for outgoing PPP connections (null terminated). FFFF F03E B074 4 UI Maximum connection time in seconds. Default is 0 (disabled). Maximum amount of time an outgoing PPP connection can stay connected after successful negotiation. SNAP Ethernet-Based I/O Units Protocols and Programming Guide 117
