Thanks so much, that's what I was looking for.

Edit: It works on Linux & AIX (Pretty sure it's running off GNU SED), doesn't work on Solaris by default. Any tips on Solaris, or alternate syntax? If it's not possible without GNU SED that's fine, just checking up.

Code:
# uname -s
SunOS
# echo "This is a test 0A2B9C 0A 3B4C" | sed 's/\([0-9][A-Z]\)\{1,3\}/X/g'
This is a test 0A2B9C 0A 3B4C

vs. Linux
Code:
$ uname -s
Linux
$ echo "This is a test 0A2B9C 0A 3B4C" | sed 's/\([0-9][A-Z]\)\{1,3\}/X/g'
This is a test X X X

vs. AIX:
Code:
# uname -s
AIX
# rpm -qa|grep sed
sed-4.1.1-1
# echo "This is a test 0A2B9C 0A 3B4C" | sed 's/\([0-9][A-Z]\)\{1,3\}/X/g'     
This is a test X X X

irdaping

IRDAPING(8)															       IRDAPING(8)

NAME

       irdaping - sends IrDA test frames

SYNOPSIS

       irdaping [ daddr ] [ -s framesize ]

OPTIONS

       daddr ...

       -s framesize ...

DESCRIPTION

       This is a program similar to ping(8). It sends IrDA test frames (added some userdata which contains the frame number and the time the frame
       was sent). You can change the size of the frame by using the -s option. To get daddr you may use irdadump.

       irdaping must be run as root or installed setuid root, as it requires root privileges.

EXAMPLES

       irdaping <daddr> [-s <framesize>]

       You may use an alias, which does not use any parameter alias irping="irdaping `grep daddr /proc/net/irda/discovery|sed s/.*daddr://`"	It
       works fine when there is only one discovered client.

DIAGNOSTICS

       N.N.

BUGS
