What's up with this? I'm trying to use Windows10 PowerShell to interact with a Meteor application. I'm having a heck of a time displaying feedback from the server thru the PowerShell. Here's a typical screen shot:

PowerShell Screen Shot

At first glance it looks okay... but... what's up with that big blank zone to the left of the warning about bcrypt? Here's a simple text copy paste from that same screen.

=> Started proxy.
=> Started MongoDB.
W20160829-11:13:55.719(-7)? (STDERR) Note: you are using a pure-JavaScript implementation of bcrypt.
W20160829-11:13:55.780(-7)? (STDERR) While this implementation will work correctly, it is known to be
W20160829-11:13:55.782(-7)? (STDERR) approximately three times slower than the native implementation.
W20160829-11:13:55.785(-7)? (STDERR) In order to use the native implementation instead, run
W20160829-11:13:55.787(-7)? (STDERR)
W20160829-11:13:55.789(-7)? (STDERR)   meteor npm install --save bcrypt

I'm thinking its a Polar Bear in a Snow Storm issue. The raw server feedback data is there, you just can't see it. The copy of the server log errors and time are written in exactly the same color as the background. I've made changes to background color, but none of them seem to work very well. It's not clear to me on where those settings for that class of message exist. Here's my properties pull down box:

PowerShell Properties Box

As you can see I only have options for Screen Background/Text colors and Popups background / Text colors. It's like those server warnings are a different classification of output. One that I am unable to even identify or modify. Anybody know what is going on here? Is there a way to fix this so I can easily see ALL the feedback from the server?

And yes, I'm doing development, so I'm running this localhost, Windows 10.

I'm trying to figure out if there is a way to do a non-invasive test on different networks to see if Universal Plug'n'Play (nPnP) is enabled at the router. i.e. Is Internet Gateway Device Profile implemented at the router? I'm thinking of a webpage test, but without any sort of downloaded executable... (I don't want to put any fear in the hearts of systems admin and IT guys!)

A user, inside the network, would open up a link in a browser, and then JavaScript on the page checks UDP via discovery message. The only reference I've seen on this possibility is

When a UPnP capable device joins a network and wants to know what UPnP services are available on the network, it sends out a discovery message to the multicast address 239.255.255.250 on port 1900 via the UDP protocol. This message contains a header, similar to a HTTP request. This protocol is sometimes referred to as HTTPU (HTTP over UDP):

M-SEARCH * HTTP/1.1 HOST: 239.255.255.250:1900 MAN: ssdp:discover MX: 10 ST: ssdp:all

All other UPnP devices or programs are required to respond to this message by sending a similar message back to the device, using a UDP unicast, announcing which UPnP profiles the device or program implements. An interesting quirk: it is sent back with UDP unicast to the port the device discovery message was sent from. For every profile it implements one message is sent:

HTTP/1.1 200 OK CACHE-CONTROL:max-age=1800 EXT:
LOCATION:http://10.0.0.138:80/IGD.xml SERVER:SpeedTouch 510 4.0.0.9.0
UPnP/1.0 (DG233B00011961)
ST:urn:schemas-upnp-org:service:WANPPPConnection:1
USN:uuid:UPnP-SpeedTouch510::urn:schemas-upnp-org:service:WANPPPConnection:1

I know how to create sockets and more common forms of communication (http) via JavaScript in the browser, not sure how to communicate via UDP. Anybody have any ideas? Is anyone aware of a uPnP config testing tool existing today?

I've found a few responses on StackOverflow but they are pretty pessimistic. e.g. here
