Characteristics of the low speed port
Ports 0 and 2 are asynchronous, low speed ports. They transfer data to
and from the line one bit at a time.
The characteristics of the low speed port are as follows:
•Baud rate: 300; 600; 1200; 2400; 4800; 9600; 19,200
Default = 1200
•Parity: Odd, even, none
Default = none
• Stop bits: 1, 1.5, 2
Default = 1
•Flow control: XON/XOFF, CTS, non.
Default = none
•Duplex: Full
•Interface: RS-232-D
•Data bits: 5, 6, 7, 8
Default = 8
Characteristics of the high speed port
Ports 1 and 3 are synchronous, high speed ports with the following
characteristics:
•Baud rate: 1200; 2400; 4800; 9600; 19,200; 56,000; 64,000
