I encountered some problem: there is a trivial program on Go that writes to the files / dev / eiaU4 / eiaUctl and / dev / eiaU the control parameters and data respectively. But in fact the records are not produced at all, it is known that this has nothing to do with the program itself.
Are there any ideas how to tackle the problem?Thanks ! It's really works !2018-08-14 15:16 GMT+03:00 Richard Miller <9fans@hamnavoe.com>:> mk: don't know how to make 'acm.h' in directory /sys/src/cmd/usb/serial
Sorry, I thought that was already in the distributed version. I've updated
the serial.tar file, so it should be complete now if you try again.

Set the baud rate with
echo b9600 >/dev/eiaU?/eiaUctl
and then you can receive data with
cat /dev/eiaU?/eiaU
or set up an interactive conversation, as Steve Simon suggested, with
con /dev/eiaU?/eiaU
More information is in the manual - uart(3), usb(4), con(3)
