Het probleem van het hangen van de TX icon is opgelost.
Procedure:
Set uit.
Power en USB fysiek afkoppelen (stekkers er uit)
Tot 30 tellen.
PWR er weer op. Inschakelen en usb weer plaatsen.
That’s it !

Once upon a time somewhere in 2015 i bought a couple of these little converters RS232 tot TTL.
Here is how they work
From the RS232 Port – RX, TX and GND. Thats the -> -<and the – signs. Easy enough
– GND
-> RX
<- TX
On the TTL (Arduino) side – DO NOT USE 5V use 3.3V as this toasts the device and heats up and like tops itself. It certainly got very toasty when I put 5V across it. This could be because I messed up somewhere in the wiring but it certainly works well for me. I can also use the SoftwareSerial library as well so I don’t need to use TX/RX on the TTL Serial pins 0 and 1
So TTL is
– GND
-> – PIN X
<- PIN Y
For my device I used PIN 0 and PIN 1 – TX/RX – but I guess you can use other pins.
Hope this helps – it does work!
Often i buy myself some small gadgets, only to forget about them .This plcae is my storage of these items and their technical descriptions etc

Just before years end i have compiled the latest OpenWRT LEDE & APRX, and added OpenVPN and OpenSSL to it. The files can be found in the download section. If you have another router, then drop me a line, or call me at DMR at 204 / 2044 or 2045.
I have added new firmware packages and the latest APRX package in the download section. In case you need firmware for another router, please let me know and I see what I can do.
To install just the package, do as follows….
ssh into your machine (normally something like sss root@(ip-of-machine)
Then change into the tmp directory and execute:
/etc/init.d/aprx stop
wget https://www.pa0esh.com/svn/aprx_2.9.0-Stable_brcm47xx.ipk
chmod 755 aprx_2.9.0-Stable_brcm47xx.ipk
opkg install aprx_2.9.0-Stable_brcm47xx.ipk
In case the installer tells you that you have already the latest package, change the command into:
opkg install aprx_2.9.0-Stable_brcm47xx.ipk –force-download
Erik, pa0esh
The script to install and maintain the md380tools has been updated to version 3.2.
New is that the script checks if there is an update available from GitHub.
The latest firmware images for Openwrt & APRX have been uploaded in januari 2017. See the download section.
Ans see Google groups for more info…. https://groups.google.com/forum/#!forum/aprx-software

You can test which version you are running:
type aprx -V from the prompt
currently on openwrt the version nummer is not correct but instead will show: 5.05-333-g160eb5d
/etc/init.d/aprx restart
I have updated and recompiled the APRX / OPENWRT images and the APRX packages on the 8th of August 2016. You will find them in the download section.
Currently running attitude adjustment, 15.05 and trunk of Openwrt with aprx at : 2.8.2-16-ge529aaf.
If you need images for another router, please let me know.
