The Communication Settings parameters let you set the
baud rate, parity, stop bit and data length for the first
serial port (COM 1). The values are as follows:
•
Baud rate: 300 to 38,400 bits per second (BPS)
•
Parity: odd, even, or none
•
Stop bit: 1 or 2 stop bits
•
Data length: 7- or 8-bit data word
There is one restriction on the options available for the
communication status parameters. If your data length
parameter is an 8-bit data word, you must select one of
the following combinations:
•
1 stop bit and odd or even parity
•
2 stop bits and no parity
The default values are 9600 BPS, odd parity, 1 stop bit,
and 8-bit data word.
This function enhances disk performance depending on
the fixed disk in use. If you set this parameter to
Enabled, it allows data transfer in block (multiple
sectors) by increasing the data transfer rate to 256
bytes/cycle. If your system does not boot after enabling
this parameter, change the setting to Disabled. Disable
the parameter if your system disk does not support this
function.
Enabling this parameter allows for faster data recovery
and read/write timing that reduces Fixed Disk activity
