ppp.Dialers - PPP dialer description file format DESCRIPTION
The file describes how to dial each type of modem attached to the UNIX system that is to be made available for outbound PPP calls. exam- ines it when placing a call to a neighboring machine. When selects a line from it uses the field to select an entry in from which it uses the field to select an entry in then interprets the field from that dialer description. Format Entries are one to a line; blank lines are ignored. Comments begin with a and extend to the end of the line. Upper/lower case distinc- tions in the dialer field are significant for matching purposes, as are strings in the chat script. Fields on a line are separated by hor- izontal white space (blanks or tabs). If a chat script ends with a backslash the next line is considered a continuation of the chat script. Continuations may only occur in the midst of a chat script. Each entry must contain these fields, in this order: dialer The name of this dialer, to be matched against the dialer field in chat-script A description of the conversation that holds with the modem. Chat Script Particulars A chat script takes the form of a space-separated list of expect-send pairs. Each pair consists (at minimum) of a field to expect the end to send, then a field to send in response. Unless a string ends with will follow it by sending a carriage return character (ASCII 0x0d). Chat scripts are or where the following the hyphen is executed if the preceding fails to match received text. Certain special words may be used in the chat script to control the behavior of as it attempts to dial. Both ABORT and TIMEOUT must be in the phase of the chat script. If sees abort-string while executing the remainder of the chat script, abort the dialing attempt and note the failure in the log file. While executing the current chat script, wait timeout-time seconds for a response before considering the dialing attempt to have timed out. Writes have a fixed 60-second timeout. The expect-send couplet of 'sets the line parity accordingly: Set transmission parity based on the parity observed in characters received in strings. This is the default. Transmit characters with the parity bit set to zero (8 bits, no parity). Transmit characters with the parity bit set to one. Transmit characters with even parity. Transmit characters with odd parity. In the midst of either an string or a string, gets translated into the appropriate control character, and gets translated into x. Other special sequences are: Send or receive a space character (ASCII 0x20). Send or receive a horizontal tab character (ASCII 0x09). Send or receive a line feed character (ASCII 0x0a). Send or receive a carriage return character (ASCII 0x0d). Send or receive a backslash character (ASCII 0x5c). Send or receive a carat character (ASCII 0x5e). Send or receive the single character Ctrl-character (ASCII 0x00 through 0x1f). Send or receive a character, specified in octal digits. Pause for .25 second before proceeding (send only). Delay for two seconds before proceeding (send only). Send a break (.25 second of zero bits). Disable hangups (sets CLOCAL or LNOHANG). enable hangups (unsets CLOCAL or LNOHANG) (the default). Don't append a carriage return character after sending the preceding string (send only). Don't print succeeding send strings (e.g., a password) in any debugging or logging output. Subsequent sequences toggle mode. Insert the telephone number (found in the fifth field of here. EXAMPLES
