In this mode, the receiver and transmitter interrupts are fully operational. The Modem
Control Interrupts are also operational. However, the interrupts can only be read using
lower four bits of the Modem Status Register (MSR[3:0]) instead of the four Modem Status
Register bits 7:4. The interrupts are still controlled by the IER.
