Re: slcanpty

Hi Janusz,

the slcanpty programm is just some kind of proof of concept to make applications
run, that use the slcan ASCII protocol.

E.g. http://www.port.de/en/products/canopen/diagnose/can-analyzer-can-report.html

which has the LAWICEL CAN hardware as possible hardware:

See at www.canusb.com

If you would like to have a "remote control" via IP networking for SocketCAN,
I would recommend the socketcand:

Please google for "socketcand", there's a video also ...
