Pipe each stdout line to a comand on windows

Can I/how do I pipe each line of output from a command to another command (on Windows).

For example I have tshark which outputs:

1   0.000000 1.1.1.1 -> 1.1.1.2 TLSv1.2 85 Application Data
2   0.000726 1.1.1.2 -> 1.1.1.1 TLSv1.2 89 Application Data
3   0.064803 1.1.1.3 -> 1.1.1.2 TLSv1 155 Application Data
4   0.155403 1.1.1.1 -> 1.1.1.2 TCP 60 443â┼'62745 [ACK] Seq=32 Ack=36 Win=374 Len=0
5   0.268586 1.1.1.2 -> 1.1.1.3 TCP 54 56149â┼'443 [ACK] Seq=1 Ack=102 Win=63331 Len=0
6   0.730557 1.1.1.2 -> 1.1.1.4 UDP 45 Source port: 46586  Destination port: 52531
7   1.069927  1.1.1.5 -> 1.1.1.2 TCP 60 40020â┼'50293 [PSH, ACK] Seq=1 Ack=1 Win=136 Len=3
8   1.179893 fe00::dd00:9f00:dd00:1e00 -> ff00::c      SSDP 208 M-SEARCH * HTTP/1.1
9   1.269580 1.1.1.2 -> 1.1.1.5  TCP 54 50293â┼'40020 [ACK] Seq=1 Ack=4 Win=16130 Len=0

And I want to execute my-prog.bat on each line, e.g:

my-prog.exe   1   0.000000 1.1.1.1 -> 1.1.1.2 TLSv1.2 85 Application Data
my-prog.exe   2   0.000726 1.1.1.2 -> 1.1.1.1 TLSv1.2 89 Application Data
my-prog.exe   3   0.064803 1.1.1.3 -> 1.1.1.2 TLSv1 155 Application Data
my-prog.exe   4   0.155403 1.1.1.1 -> 1.1.1.2 TCP 60 443â┼'62745 [ACK] Seq=32 Ack=36 Win=374 Len=0
my-prog.exe   5   0.268586 1.1.1.2 -> 1.1.1.3 TCP 54 56149â┼'443 [ACK] Seq=1 Ack=102 Win=63331 Len=0
my-prog.exe   6   0.730557 1.1.1.2 -> 1.1.1.4 UDP 45 Source port: 46586  Destination port: 52531
my-prog.exe   7   1.069927  1.1.1.5 -> 1.1.1.2 TCP 60 40020â┼'50293 [PSH, ACK] Seq=1 Ack=1 Win=136 Len=3
my-prog.exe   8   1.179893 fe00::dd00:9f00:dd00:1e00 -> ff00::c      SSDP 208 M-SEARCH * HTTP/1.1
my-prog.exe   9   1.269580 1.1.1.2 -> 1.1.1.5  TCP 54 50293â┼'40020 [ACK] Seq=1 Ack=4 Win=16130 Len=0

My my-prog.bat is simply echo %TIME% %* >> test.txt

I tried a few things like (using GnuWin xargs):

tshark | xargs my-prog.bat
tshark | xargs -n1 my-prog.bat

But the best I got was outputing litterally %* to the file. (my-prog.bat test works as expected and appends test to the file)

(Note that tshark will continue to run until CTRL+C is pressed)
