True, this is not obvious.

In the section WINDOW TYPES, we have this:

If a tty (character special device) name (e.g. "/dev/ttya") is specified as the first parameter, then the
window is directly connected to this device. This window type is similar to "screen cu -l /dev/ttya". Read
and write access is required on the device node, an exclusive open is attempted on the node to mark the con-
nection line as busy. An optional parameter is allowed consisting of a comma separated list of flags in the
notation used by stty(1):

<baud_rate>
Usually 300, 1200, 9600 or 19200. This affects transmission as well as receive speed.

[...]
Higher baud rates (38400, 57600, 115200) should be mentioned, and an example should get added to the SYNOPSIS. I am not particularly happy with the reference to cu, which is possibly less known than screen.

An introductory paragraph should be added near the top of the manual explaining the two basic usage scenarios terminal multiplexer (/dev/ttyUSB0 or '//telnet host port', typical multiuser) versus shell/application multiplexer (typical single user).

Commonly screen appears to be invoked such as this
screen /dev/ttyUSB0 115200
i.e. as screen device arg(s)
yet this is not documented so far as I can see, let alone CLEARLY

It is too good to remain that way.

Looks like info/man pages and at least exit_wit_usage could do with improving.
