| 47 * Since the USART supports RS-485 multidrop mode, it allows the 48 * TX pins to float. However, for RS-232 operations, we don't want 49 * these pins to float. Instead, they should be pulled up to avoid 50 * mismatches. Linux does something similar when it configures the 51 * TX lines. This implies that we also allow the RX lines to float 52 * rather than be in the state they are left in by the boot loader. 53 * Since they are input pins, I think that this is the right thing 54 * to do. | 47 * Unsure what all is in the HOTe HL200, but I do know there's 48 * one serial port that isn't DBGU. There's many other peripherals 49 * that need to be configured here. |
