Serial Port 10 Information

Serial Port 10 is sometimes called Serial Port B in Test Set

documentation and programs.

The default Serial Port 10 settings are the same as Serial Port 9. They

are

1. Serial Baud rate: 9600

2. Parity: None

3. Data Length: 8 Bits

4. Stop Length: 1 Bit

5. Receive and Transmit Pacing: Xon/Xoff

6. Serial in: Not available for Port 10

7. IBASIC and Instrument Echo: Not available for Port 10

There is no Test Set screen that shows Serial Port 10’s settings.

Therefore, to know Serial Port 10 settings, they must either be set or

queried using IBASIC commands.

For example, the following IBASIC program queries the baud rate

setting of Serial Port 10:

Example 8-10 Example

10 DIM Setting$[20]

20 OUTPUT 800;"CONF:SPB:BAUD?" !Initiates a query.

30 ENTER 800;Setting$

40 DISP Setting$

50 END

This program returns a quoted string. If the baud rate is set to 9600,

the returned ASCII character string is 9600. Serial Port 10 settings are

held in non-volatile memory. They remain unchanged until modified

using an IBASIC command.
