[Windump] Windump error

[Sherrit, Charles]

Hi, 
 I've just installed the latest windump and pcap . 
I can run this command successfully 
C:\>windump -i 1 port 2055 
windump: listening on \Device\NPF_{F7C4ADC1-FB6C-467E-A4AF-19432ACF11F8}

Or 
C:\>windump -i 1  -w capture
windump: listening on \Device\NPF_{F7C4ADC1-FB6C-467E-A4AF-19432ACF11F8}

But not this 

C:\>windump -i 1 port 2055 -w capture
windump: listening on \Device\NPF_{F7C4ADC1-FB6C-467E-A4AF-19432ACF11F8}
windump: syntax error

Does it make sense?
Thanks 
Chaz
