Both ports are configured as Data Terminal Equipment (DTE). Both the send and receive registers of each port have a
16-byte FIFO. All serial ports have 16C550-compatible UARTs. The RS-232 has a charge pump to generate the plus
and minus voltages so the EBC-Z5xx only re5V to operate. An independent, software programmable baud rate
generator is selectable from 50 through 115.2 kbps. Individual modem handshake control signals are supported for all
ports.
