Thank you very much, Richard! You correctly understood about the adapter. Tell me, please, how to perform the installation (there is no Internet on Raspberry Pi, but I can transfer files via drawterm)? And how do I read data (if possible, not through C)?> usb/probe result:

That's a CH341 adapter. I have a driver which should work. You can fetch an
updated usb/serial command from http://www.hamnavoe.com/usbserial (use hget).
If you want to build from source, updates to /sys/src/cmd/usb/serial are in
http://www.hamnavoe.com/serial.tar
I would put a patch on sources but the Bell Labs server is unresponsive
at present.
