good to hear that you solved the issue and thanks for reporting. I will provide a fix to
the port scan on Linux in the next version of Artisan and two more enhancements of that
feature that will be available on all platforms.

Thank you Marko!
Artisan is now working fine! Your mail got me on the track. The problem was apparently
related to getting a wrong port address from Artisan scanport + possibly permissions.
I'Il explain a little bit in case somebody else faces this problem later.
1. After scanning ports in Artisan, I had "/dev/cu.usbserial-FTFKDA5O" in the
drop down menu. I selected this port.
2. When clicking 'ON', I got the following message: "Serial Port Setting:
/dev/cu.usbserial-FTFKDA5O, 19200, 8, E, 1, 1"
3. After typing "sudo chmod 666 /dev/cu.usbserial-FTFKDA5O" in the console I
had a message that the device doesn't exist. Apparently the port name I got from
Artisan scanning feature was wrong.
4. In terminal, by listing the content of dev folder, I observed that entry
'ttyUSB0' appears only if the Amprobe logger plugged in. I assumed this is the
port name to use instead of what Artisan showed.
5. I changed permissions with 'sudo chmod 666 /dev/ttyUSB0'
6. Back in Artisan, after scanning for ports, I selected
'/dev/cu.usbserial-FTFKDA5O' and manually changed it to '/dev/ttyUSB0'. It
I hope this can help. Maybe something related to the first error message I reported:
"Exception: scanforport(): global name 'base' is not defined @ line

Might be a permision problem. The account you run
Artisan on might not be allowed to write to that device.

Betreff: [Artisan-user] Help Linux + Artisan 0.6 + Amprobe TMD56: Serial exception:
Unable to open serial port
In case this additional information can help identifying the problem.
I installed Artisan 6 on Debian (instead of Ubuntu originally) on the
same laptop and I get an identical problem with my Amprobe TMD56:
Serial exception: Unable to open serial port
(1) Is there a log or configuration document that I could post to help
troubleshooting the problem?
(2) Is there a terminal tool or command to monitor the in/out traffic
with Amprobe logger?
(3) Is there anything I need to do to the TMD logger other than
setting channel to 0, plugging to usb and turning on???
Thank you for your help.

Thanks for your reply. With the Amprobe plugged in and turned on,
if I select FTFKDA5O then click OK the message is:
"Serial Port Setting: /dev/cu.usbserial-FTFKDA5O, 19200, 8, E, 1, 1"
If I click ON then I get the following error message:
"Serial Exception: Unable to open serial port"
Amprobe shows 2 temperatures (in C) but Artisan display shows zero.
Artisan plot graph scale seems to be configured (default) to F but
I don't think this should be an issue anyway. Is there another test
I could do to help figure what the serial port issue is?
Thanks for your help & best regards from Montreal.
