Graceful restart of Trunk Recorder

[blantonl]

Does anyone know of a way to gracefully restart trunk recorder without having to reboot your machine?

Seems like the only way stop trunk-recorder is to Cntrl-C it, and then reboot the machine because the RTL drivers are all borked up.

I have used Trunk Recorder for about 3 years. My restart habit works as follows:
CNTL-C to exit
Wait about 20 seconds
Hit the UP arrow to reload the previous command line and hit Enter.

Since trunk recorder has no automated gain control I find it frequent that I have to edit my config.json file with a different sdr gain value. This is where I exit trunk recorder, wait 20 seconds for the dongles to release, launch GQRX and find an appropriate gain setting, edit the config.json file, then re-launch trunk recorder with up arrow then enter.

On mine I can just x the terminal and then restart?

Hmm, maybe I'm just not being patient enough and waiting 20 seconds. I'll give that a shot. Thanks!

I wonder if going into Device Manager and going to Human Interface Devices, then right click the device and disable/enable will do the trick? There's also some form of USB cache, but I have to find that Info. again from a computer forum I'm a member of. I'm thinking clearing that cache may help, too.

USBdeView might work as well. But that might not be such a good idea when you need that certain driver (can't remember its name now) for the SDR. View any installed/connected USB device on your system

This is all Linux I’m referring to - not Windows

My bad. Sorry, I assumed in shame that you were using Windows. Perhaps Linux, too has a USB caching mechanism that can be reset in an effort to reset the "com port" so a hard computer/OS restart is not needed.

I'm affraid my Linux knowledge is very limited so I'd have to do some digging on that one. I have however manged to install a LAMP stack and Webmin in a virtualized CentOS one day, but I have no idea what all the terminal commands are and have bookmarked all of that.

Let me see if I can fix this up. I think it can hang if it is not decoding any messages.

If you open another tab in the Terminal and list the processes doing `ps -a` and then `kill` the process, that should work.
