I\'m now doing it this way:

0000000 6141 000a                              
0000003
[root@~]# echo -e \"\\x41\\x41\\x41\\x41\"
A

here a little script I wrote to convert ascii to hex. hope it helps:

echo '0x'"`echo 'ASCII INPUT GOES HERE' | hexdump -vC |  awk 'BEGIN {IFS="\t"} {$1=""; print }' | awk '{sub(/\|.*/,"")}1'  | tr -d '\n' | tr -d ' '`" | rev | cut -c 3- | rev
