                     14: .I Slconfig
                     15: is used to define or to tear down a point-to-point link 
                     16: between two hosts via a serial interface. It
                     17: must be used at boot time to define the network address
                     18: of each serial interface present on a machine; it may also be used
                     19: to redefine an interface's address at a later time.
                     20: .PP
                     21: To add or redefine a serial interface, evoke 
                     22: .I slconfig
                     23: with the flag -a. To detach an interface from the network, evoke
                     24: .I slconfig
                     25: with the flag -d.
                     26: .PP 
                     27: The
                     28: .I ttyname
                     29: parameter is a terminal-device name, e.g., '/dev/ttyxx' or 'ttyxx'.
                     30: .I Slconfig
                     31: assigns a network interface name to the added serial line, e.g., the 
                     32: first added serial interface will be assigned
                     33: interface name 'sl0', the second 'sl1', and so on. The user must specify 
                     34: the assigned interface name when tearing down the link.
                     35: .PP 
                     36: The
                     37: .I source-hostname
                     38: and
                     39: .I destination-hostname
                     40: parameters specifies the source and destination hostnames which must
                     41: be defined in the database
                     42: .I /etc/hosts.
                     43: .PP 
                     44: The
                     45: .I interface-name
                     46: parameter is a string of the form 'slx', e.g. 'sl0'.
                     47: .PP 
                     48: The
                     49: .I baudrate
                     50: parameter is optional; the default baudrate is 9600.
                     51: The file 
                     52: .I <sys/ttydev.h>
                     53: contains the valid baudrates except for 
                     54: .I EXTB. 
                     55: WARNING: The baudrate selected has to be matched in both source and 
                     56: destination hosts for the serial interface to work properly.
                     57: .PP
                     58: Only the super-user may modify the configuration of a network interface.
