How about this:

Code:
awk '
/^primary$/ {ARMED=1}
ARMED==1 && /^\*/ {SLOT=$2}
$1="Slot" && $2==SLOT{ARMED=2}
/^Touch:/ && ARMED==2{print "Slot " SLOT;print; SLOT=ARMED=0}' infile

slattach

SLATTACH(8)						    BSD System Manager's Manual 					       SLATTACH(8)

NAME

     slattach -- attach serial lines as network interfaces

SYNOPSIS

     slattach [-Hhlmn] [-s baudrate] [-t ldisc] ttyname

DESCRIPTION

     slattach is used to assign a tty line to a network interface which uses asynchronous serial lines.

     Currently the slattach command is used to attach sl(4) or strip(4) interfaces.  These interfaces have to be created using the ifconfig(8)
     create subcommand before the slattach command.  The network source and destination addresses and other interface parameters are configured
     via ifconfig(8).

     The following operands are supported by slattach:

     -H 	   Turn on DTR/CTS flow control.  By default, no flow control is done.

     -h 	   Turn on RTS/CTS flow control.  By default, no flow control is done.

     -l 	   Turn on the CLOCAL flag, making it possible to run SLIP on a cable without modem control signals (e.g. DTR, DSR, DCD).

     -m 	   Maintain modem control signals after closing the line.  Specifically, this disables HUPCL.

     -n 	   Don't detach from invoking tty.

     -s baudrate   Specifies the speed of the connection.  If not specified, the default of 9600 is used.

     -t ldisc	   Specifies the line discipline to use for the tty.  Supported line disciplines are ``slip'' (creates a sl(4) instance) and
		   ``strip'' (creates a strip(4) instance).  If this option is not specified, the default is ``slip''.

     ttyname	   Specifies the name of the tty device.  ttyname should be a string of the form 'ttyXX', or '/dev/ttyXX'.

     Only the super-user may attach a network interface.

     To detach the interface, use ``ifconfig interface-name down'' after killing off the slattach process.  Interface-name is the name that is
     shown by netstat(1).

EXAMPLES

	   slattach ttyh8
	   slattach -s 4800 /dev/tty01

DIAGNOSTICS

     Messages indicating that the specified interface is not configured or created, the requested address is unknown, or that the user is not
     privileged but tried to alter an interface's configuration.

SEE ALSO

     netstat(1), daemon(3), netintro(4), sl(4), strip(4), ifconfig(8), rc(8), sliplogin(8), slstats(8)

HISTORY

     The slattach command appeared in 4.3BSD.

BUGS

     There is no way to specify the interface name (sl%d etc.) to be attached by the slattach command.	There is no way to see which interface is
     assigned to the specified tty by the slattach command, either.

     It would be better if the network interfaces were created by the slattach command rather than by using the ifconfig(8) create subcommand
     before the slattach command.
