Hello!

Is it any chance of create a legato app that permits serial communication? We have already created a program with le\_tty functions (le\_tty\_open, le\_tty\_close, …) but we cannot use the ports ttys0, ttys1 properly. The app runs with ttyHSL1 but in windows it does not exist any COM port associated to that ttyHSL1.

Regards,

Pablo
