NAME

x3config − PAD-related X.3 configuration file

DESCRIPTION

x3config is an ASCII file in directory /etc/x25 that contains X.3 configuration information for X.25 PAD (packet assembler/disassembler) components padem, x29printd, x29server, and x29uucpd. x3config contains many different terminal-specific characteristics or actions that the hosts want the remote PAD, PAD support, or PAD emulation to take upon receipt of specific input from the hosts or from the remote PAD device.  x3config contains different configuration groups that the user can choose to use as initial X.3 parameters.  The groups of X.3 parameters are referenced by X.3 configuration set names in the file /etc/x25/x29hosts. 

x3config contains the following information:

• X.3 Configuration Set Name

• X.3 Parameter

• Corresponding Parameter Value

• Comment Lines

The x3config file is made up of one or more X.3 configuration sets.  Each X.3 configuration set has its own configuration entry consisting of X.3 parameters and corresponding values (each parameter-value pair on a separate line) enclosed in curly braces {}, and preceeded by the X.3 configuration set name (and profile).  The X.3 configuration set name is defined by the administrator, and maps to the PAD configuration entries in file /etc/x25/x29hosts.  The administrator can also define profile identification numbers profile_ids for X.3 configurations.  prof_id is an integer number that is used by padem as the method of referencing X.3 configurations.  prof_id immediately follows x3_config_set_name and a colon (:).  A typical X.3 x3config configuration set is constructed as follows:

x3_config_set_name {
# <X.3 parameter> <value1> <value2>
         1           1        1
         2           1        1
         .           .        .
         .           .        .
         .           .        .
        22           0        0
}

Parameter interpretation is as follows:

x3_config_set_name A string that identifies the accompanying set of parameter-value pairs enclosed within curly braces.  Each X.3 configuration set name should be unique.  x3_config_set_name must be concatenated with a profile ID when defining the X.3 configuration for padem (see padem(1)).

X.3 Parameter An integer whose value ranges from 1 through 22 and defines the type of X.3 parameter the user is requesting. 

Parameter Value Assigns a value to the corresponding X.3 parameter.  Only certain values are recognized for each specific X.3 parameter.  value1 refers to line-mode processing.  value2 refers to raw-mode processing. 

Comment Lines Comment lines begin with a # character, and any characters following the # character are treated as comments (ignored). 

X.3 parameters are initially set from the x3config file.  They can also be set by applications that rely on specific terminal I/O options.  X.3 parameters are used to control I/O options between the host and the PAD device, and are analogous to host-to-terminal I/O options.  For example, baud rate and parity must be set to appropriate values before a host and terminal can communicate correctly.  X.3 parameters provide a means for defining how communication is to be handled between the host and the PAD.
