Returned lines overlap when using ncat pipe in a shell script

I am using /bin/sh to write a shell script that fetches data from a telnet call via ncat, like so:

echo 'transport info' | ncat hostname 9993

When I do this from a command line the output looks like this:

500 connection info:
protocol version: 1.3
model: HyperDeck Studio

208 transport info:
status: record
speed: 0
slot id: 1
clip id: none
display timecode: 00:28:01:27
timecode: 00:00:00:00
video format: 1080i5994
loop: false

But when I do it in a shell script /bin/sh it looks like this:

loop: falseat: 1080i599443:15

Here is my sample script:

#!/bin/sh
FOO="$( echo "transport info" | ncat -C hostname 9993 )"
echo $FOO

Anyone know why this happens?

#!/bin/sh
echo "transport info" | ncat -C hostname 9993 | dos2unix > /tmp/test.txt
cat /tmp/test.txt

Output:

500 connection info:
protocol version: 1.3
model: HyperDeck Studio

208 transport info:
status: preview
speed: 0
slot id: none
clip id: none
display timecode: 01:10:01:01
timecode: 00:00:00:00
video format: 1080i5994
loop: false
