альтернативный Linux getty (alternative Linux getty)
Ошибки (баги) (Bugs)
The baud-rate detection feature (the --extract-baud option)
requires that agetty be scheduled soon enough after completion of
a dial-in call (within 30 ms with modems that talk at 2400 baud).
For robustness, always use the --extract-baud option in
combination with a multiple baud rate command-line argument, so
that BREAK processing is enabled.
The text in the /etc/issue file (or other) and the login prompt
are always output with 7-bit characters and space parity.
The baud-rate detection feature (the --extract-baud option)
requires that the modem emits its status message after raising
the DCD line.
