- 1) general info
-
- LSppp is a small MSDOS PPP packet driver. It is compatible with the
- needs of WATTCP and trumpet stacks. The resident size is approximately
- 28K.
-
- LSppp loads as a class one ethernet driver and handles all
- aspects of the connection from dialing onward. Optionally, an external
- dialer may be used to dial an ISP prior to running LSppp; it will
- detect the carrier and go immediately into internet communications
- setup.
-
- LSppp is capable of auto-configuring WATTCP through the bootp mechanism
- and will do so automatically. However, for this to work properly LSppp
- will have to be supplied with name server information. LSppp will
- attempt to automatically load name server information from the ISP
- if none is specified on the command line, however, this is an optional
- feature your ISP may not support. To see if it is supported run LSppp
- without specifying the name server switch (/N) and see if it places
- DNS addresses in the IP-UP.bat file
-
- LSppp does not use configuration files; all parameters are placed on
- the command line or optionally in the LSPPP environment variable.
- LSPPP will search the environment variable for valid command switches
- first, then modify this information with command switches specified on
- the command line. Configuration options include user name and
- password, number to dial, nameserver information, and various options
- to set up a communications port to use or customize the timeout
- mechanisms.
-
- The current version does not have a lot of backwards compatability for
- old versions of the protocols. If you have problems running it use the
- undocumented /z switch and send the resulting LSPPP.LOG file to the
- author for analysis. Note that to get a log file you MUST use the /z
- switch; the /l switch is now used for local mode
-
- Van jacobsen compression and the CHAP protocol have recently been added
- to LSPPP. Other less used protocols (including MSCHAP) are not
- currently supported.
-
- Note that the undocumented /l option has been changed to the
- undocumented /z option. Use of the new /l option will in general cause
- internet connections to not work.

- 3) Configuration
-
- When dialing the modem sends the following configuration string:
-
- ATZ
-
- Also if /dm:# is specified the modem will be told to mute the speaker.
-
- At any time before LSPPP goes resident, you may press 'esc' to end the
- session and hang up.
-
- Configuration options are as follows:
-
- /a:$ set async map
- set an asynchronous control map. Characters in the map will be
- treated as purely control characters and will be escaped during
- transmission. For example if the modem uses XON and XOFF you
- would specify a map of 0x000A0000.
- The default is a map of zero, meaning no characters are escaped.
-
- /b:$ Comm port
-
- Set a base i/o port. For example /b03f8
- default: /b:03f8
-
- /d[r][m][f][l][e]:* Dial [redial] phone number
-
- Set the phone number to dial. The redial option is not
- supported yet. The 'm' option tells lsppp to mute the speaker.
- The 'f' option forces it to dial even when it thinks it is
- already connected (useful with winmodems). The 'l' option
- causes lsppp to initially attempt a terminal-mode login before
- attempting to connect with the PPP protocol. The 'e' option
- causes lsppp to dial with 'ATX3D' instead of 'ATD', which
- should be useful in Europe where no dial tone exists.
- Example: /d:5551214
- Example: /d:P5551214 this does pulse dialing
- default: LSPPP does not dial
-
- /h or /?
-
- Displays the help text
-
- /i Comm IRQ (0-15)
-
- Set the interrupt vector to use
- example : /i:4
- default: /i:4
-
- /l Local mode
-
- Forces LSPPP to not dial (local mode connection)
- Also turns off use of modem control signals
-
- /m:#,# set MRUs
-
- sets the maximum recieve unit for both sides of the link.
- The first number is what the number which this client can transmit
- which will be passed to the TCP stack; the second number is the
- amount this client can receive.
-
- default: /m:576,576
-
- /n:# Comm port
-
- Set the com port (1-4). Automatically sets the /b and /i
- options based on the setting.
-
- example: /n:1
- default: /n:1
-
- /p ppp driver interface
-
- set the driver to use the native PPP packet interface. By default
- LSPPP will use the non-native class 1 ethernet interface. Using the
- native PPP interface has slightly less overhead than using the class 1
- interface, for those TCP stacks that support it.
-
- /u Unload TSR
- unloads the tsr
-
- /x xon/xoff
-
- use the xon/xoff protocol instead of modem control signals
-
- /A:#,# PAP timeout and count
-
- Set the timeout and count governing password authentication.
- The timeout is in seconds and is the time between retries; when
- count retries have been done LSPPP will give up. default:
- /A:3,10
-
- /B:# Baud rate
-
- Set the baud rate
- example: /B:57600
- default: /B:19200
-
- /D:#,#,# Dial timeout & count & delay
-
- Set the timeout and retries for dialing. This is the time
- LSPPP will wait for a connection (in seconds) and the number of
- retries to make before LSPPP gives up entirely. The third
- parameter is optional and is the number of seconds after
- dialing before it tries to connect to the ISP.
-
- default: /D:45,1,0
-
- /F:#[,#] UART Fifo buffering
-
- Set the buffering level of the Uart's receive and possibly transmit
- fifo (if present). Valid values for receive fifo are are 1,4,8, and 14.
- If the transmit fifo setting is present, valid values are 1-16
-
- default: no fifo usage
-
- /I:#,# IPCP timeout & count
-
- Set the timeout and count governing IP configuration.
- The timeout is in seconds and is the time between retries; when
- count retries have been done LSPPP will give up.
- default: /I:3,10
-
-
- /L:#,# LCP timeout & count
-
- Set the timeout and count governing initial link configuration.
- The timeout is in seconds and is the time between retries; when
- count retries have been done LSPPP will give up.
- default: /L:3,10
-
- /M:* Modem init string
-
- Specify a string to use to initialize the modem when dialing.
- A typical example is AT&F to initialize defaults. Note that
- the dialer will always send ATZ prior to sending the initialize
- string, which resets the modem. Also the 'm' parameter on the
- dialer can be used to automatically send ATM0 (mutes the modem)
- in addition to this initialize string
-
- default: no initialization string used
-
-
- /N:@[,@] DNS address
-
- Set the DNS name server address[s]. First address is primary
- and second address is secondary. If no name servers are
- specified LSPPP will attempt to auto-configure them from the
- server.
- example: /N:198.77.33.2,198.77.33.1
- default: /N:0.0.0.0,0.0.0.0 (autoconfigure)
- /P:* passwd
-
- Set the login password
- example: /P:truely
- default: no login password
-
- /S:@ Suggest address
-
- Suggest an IP address for the server to assign to LSPPP
- example: /S:199.62.66.44
- default: no address suggested
-
- /U:* User name
-
- Set the login user name
- example: /U:dinosaur
- default: user name
-
- /V:$ Packet driver vector
-
- Set the packet driver vector to use
- example: /V:60
- default: LSPPP searches for a free vector
-
-
- An example of a valid command line is:
-
- lsppp /dm:5551214 /n:3 /B:57600 /N:101.202.101.4 /U:myname /P:mypass
-
- which uses COM3 to log into an ISP at 57600 BPS with account 'myname'
- and password 'mypass'. A nameserver is specified and the speaker will
- be muted.
-
- If we had performed the following to set the LSPPP environment
- variable:
-
- set LSPPP=/n:3 /B:57600 /U:myname /P:mypass
-
- Then typing
-
- lsppp /dm:5551214 /N:101.202.101.4
-
- would have the same effect as the first commmand line since LSPPP will
- read the environment varible before reading the command line. Of
- course you can put the number to dial and nameserver in the environment
- too.
-
- LSPPP will also read from the file LSPPP.CFG which is in the same directory
- as LSPPP.EXE. Format parameters the same as before on as many lines as
- you want.
