What has agetty to do with not being able to access a port?

Besides, the wrong baud rate wouldn't preclude a program from *reading*
from a serial interface. It would just get garbage, that's all.

Besides, a wrong baud rate would much less explain that writing is
possible, but reading isn't. Not for classical "serials" (i.e. RS-232).
