serial.databits
Attribute Character width (data bits) for the RS-232 port.
Usage
bits = serial.databits
serial.databits = bits
bits
Remarks • A new data width setting takes effect when the command to change it is processed.
• The user should allow ample time for the command to be processed before attempting to
communicate with the instrument again. It is recommended that the data width be set
from the GPIB interface or from the front panel.
• The data bits value is stored in non-volatile memory. The reset function has no effect on
data bits.
Details See "RS-232 interface
Also see serial.baud, serial.flowcontrol,
Sets data width to 8:
Example
serial.databits = 8
serial.flowcontrol
Attribute Flow control for the RS-232 port.
Usage
flow = serial.flowcontrol
serial.flowcontrol = flow
Set
flow
"none"
"hardware"
Remarks • A new flow control setting takes effect when the command to change it is processed.
• The user should allow ample time for the command to be processed before attempting to
communicate with the instrument again. It is recommended that the flow control be set
from the GPIB interface or from the front panel.
• The flow control value is stored in non-volatile memory. The reset function has no effect
on flow control.
