;Reset SR. Interrupts
;possible at levels 0-7
;UART0 receiver reset
;UART0 transmitter reset
;UART0 Mode register reset
;this sets the pointer to UMR1
;set up the UMR1 (UART0 mode register)
;for no parity, 8 bits per character
;the receiver interrupt mode is set for the
;RxRDY condition (one character received)
;After writing to this register, the mode
;pointer points to UMR2
;set up the UMR2 (UART0 mode register)
;for normal mode, 1 stop bit
;the transmitter and receiver are both
;clocked using the system bus clock (BCLKO)
;Disable interrupts for the COS & /CTS
;enabled receiver interrupt
;program dividers for 19200 baud rate
