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.
