| void __serial_console_bad_constant_port | ( | unsigned int | port | ) |
For internal use only.
Undefined function which will cause a linker error if serial_console_init() is called with a constant and invalid serial port ID.

Initialize a serial console.
- Parameters:
-
con The console to be initialized port The serial port ID to use baud_rate The initial baud rate of the serial port flags Bitmask of flags specifying additional configuration parameters.
- Returns:
- 0 on success, or a negative error code on failure.
- Note:
- Defined partially inline because port and flags will usually be constant.
