Cannot detect HP 7550A

[aleray]

Hello,

I'm having an issue with plotter detection. My HP7550A is connected using a serial to USB adaptor. It is mounted on ttyUSB0. I chmod 777 ttyUSB0 to make sure I have permissions.

Chiplotle figures out that ttyUSB0 is up but then does not manage to establish a communication with the plotter. And I get this message:

☻  chiplotle

Scanning serial ports...
Found ports:
  /dev/ttyS0
  /dev/ttyUSB0

Sniffing for plotters in all serial ports...
Found no plotter connected to any of the serial ports.
Is your plotter on?

Do you have any idea of what could be the trouble? Can it be related to my configuration file?

Thanks

Hi Alexandre, You should probably ask questions like this on the chiplotle mailing list at chiplotle.org The first thing I would check is that you have a correctly wired plotter cable. Unfortunately there are lots of variations in cable configurations out there! Only one will work with these plotters. Best, Douglas

Hello Douglas.

My cable is probably right since I can use my plotter from Inkscape.

But anyway, I just send a mail to the mailing-list as you advised. Continuing the disccusion there then. If I manage to solve my issue I'll try to post the solution here for the record.

Thanks again!

Alex
