I found that on my ASR9000 router every time I hit the up arrow I got the following errors:
Invalid number(-48) sent as ASCII value to command-line process from VTY/TTY, refreshing prompt.
Invalid number(-95) sent as ASCII value to command-line process from VTY/TTY, refreshing prompt.
It seems that Cisco recommends setting the stop bits to 2, which can be done with:
1 2 3 | configure line console stopbits 2 commit |
I then set my console port to use 2 stop bits.
After that, everything was right as rain!
This week Greg, Dave, and Mike (Déjà vu) yarn for a bit; stay a while, and listen.

I wanted the ability to conveniently PoE power radios out in the field, which to me, means via USB. I started doing some googleing, and couldn’t find anything, so here’s a quick tutorial on how to build one of your own. It takes any USB input(either via your laptop* or a booster pack), and spits out 24V power. I put an asterisk by powering it via laptop. As Faisal pointed out, if you use a high wattage radio(or other device) via this on your standard USB interface it may pull too much current and damage your port. It’s for this reason I only use my laptop for very low wattage kit like hap ac lites and the like. If you are going to power something large use a 5V 2A boost battery pack.
Here’s the quick build video:
The STL files for the 3D printed case can be found here: poe-booster-case (279 downloads)
The boost module can be found here on amazon.
The barrel jack can just be one you cut off a wall wart, or you can order some from amazon here.
***I’ve noted that the load should be connected first(hook up the radio first), then plug the USB cable into your power source. I found that some of my boost power packs don’t like it when I do it the other way round.***
Let me know if you have any questions or comments, and thanks for reading!
