* @fileoverview PC Serial Line Helpers (8250 UART 16550+).

* <p>These functions provide the baseline of PC telecommunications
* support that doesn't require switching context or cpu mode.
*
* <p>Example use cases:
* <ul>
* <li>Qemu stdio
* <li>Bare metal stdio
* <li>FIPS-170-2 SSH alternative
* <li>NIC for key-signing servers
* </ul>
