* Base Address - S700000, so ALL MC68302 on-chip peripherals begin at
* address S700xxx.
* Causes the SCC3 TXD3 and RXD3 pins to be enabled. TCLK3 and RCLK3
* pins are left as parallel l/O pins.
* SCC3 is set up for NMSI (i.e. modem) operation. No multiplexed
* modes are used on the other SCCs.
* Baud Rate generator is used for transmit and receive. Rate is 9556bps.
* No parity. Normal UART operation. 8-bit characters. 2 Stop bits.
* The CD and CTS lines not used to enable reception and transmission,
* but do cause a status change in the SCC3 Event register.
* Set up 2 Tx BDs
* Set up 2 Rx BDs
* Must be initialized to a value other than 7, or won't work with chip selects
* This combined with the “l” bit set in the Rx BD, gives interrupts on each
* character received.
* Normally set to a small value, it closes a receive buffer if a certain number
