Your RE is matching the local echo of hostname -i\r sent earlier. Try this RE .*\r\n(.*)\r\n#

For example:
Code:
set timeout 3
log_user 0
expect "# " {send "hostname -i\r"}
expect {
   -re ".*\r\n(.*)\r\n# " {set addr1 $expect_out(1,string)}
   timeout { puts "Timeout looking for TCP/IP address\n"; }
}
send "exit\r"

puts "TCP/IP address is: $addr1"

tcpser

TCPSER(1)						      General Commands Manual							 TCPSER(1)

NAME

       tcpser - emulate a Hayes compatible modem

SYNOPSIS

       tcpser -d dev -s speed [-l log_level -t tracing_options] ...
       tcpser -v port [-l log_level -t tracing_options] ...

DESCRIPTION

       This manual page documents briefly the tcpser command.

       tcpser  turns  a  PC serial port into an emulated Hayes compatible modem that uses TCP/IP for incoming and outgoing connections.  It can be
       used to allow older applications and systems designed for modem use to operate on the Internet.	tcpser supports all  standard  Hayes  com-
       mands,  and  understands extended and vendor proprietary commands (though it does not implement many of them).  tcpser can be used for both
       inbound and outbound connections.

OPTIONS

       A summary of options is included below.

       -h     Show summary of options.

       -p     Port to listen on (defaults to 6400).

       -t     Trace flags: (can be combined)
		 s	modem input
		 S	modem output
		 i	IP input
		 I	IP output

       -l     Log level: 0 (NONE), 1 (FATAL) - 7 (DEBUG_X) (defaults to 0).

       -L     Log file (defaults to stderr).

       The following can be repeated for each modem desired (-s, -S, and -i will apply to any subsequent device if not set again):

       -d     Serial device (e.g. /dev/ttyS0).	Cannot be used with -v

       -v     TCP port for VICE RS232 (e.g. 25232). Cannot be used with -d

       -s     Serial port speed (defaults to 38400).

       -S     Speed modem will report (defaults to -s value).

       -I     Invert DCD pin.

       -n     Add phone entry (number=replacement).

       -a     Filename to send to local side upon answer.

       -A     Filename to send to remote side upon answer.

       -c     Filename to send to local side upon connect.

       -C     Filename to send to remote side upon connect.

       -N     Filename to send when no answer.

       -B     Filename to send when modem(s) busy.

       -T     Filename to send upon inactivity timeout.

       -i     Modem init string (defaults to `', leave off `at' prefix when specifying).

       -D     Direct connection (follow with hostname:port for caller, : for receiver).
