SWA PARAMETERS
The SWA functions are listed in Table 4-1 and described below.
Baud Rate
The baud rate is one of seven speeds at which the MICR Plus communicates with the host. The
lowest speed is 300 baud, and the highest is 19200.
Data, Stop Bits, and Parity
Data refers to the number of data bits used to transmit every character; the options available are
7 or 8. Stop Bits refer to the number of bits used to indicate the end of transmission for every
character; the options available are 1 or 2. Parity refers to a means of detecting bit-level
transmission errors for every character; the options available are None, Even or Odd.
