You can also configure a serial port by right-clicking on its entry
in the streams list (the left-hand panel in the main window) and
selecting Configure... However, you can only do this if data has
already arrived through the port, making it appear in the
streams list.
2. The serial ports available to Scream! are listed in the table.
Identify each port, and the instrument connected to it.
If you are using Microsoft Windows, the Port number
corresponds to the COMn number of the serial port.
If you are using Linux, Port numbers 1 – 64 refer to the built-in
serial ports /dev/ttyS0 – /dev/ttyS63, and 65 and above to
USB-connected serial ports beginning /dev/ttyUSB0.
A port may not be listed if it is not installed, or suitable drivers
are not available, or if another program is using it. Scream!
scans your computer for new ports each time you open the
Setup window. To make Scream! scan the ports again, click the
Port column heading.
3. Configure each port according to the settings of the instruments
connected to them:
Baud Rate : The speed of the serial link to the instrument. If you
do not know the baud rate of your digitizer's output port, select
Auto-Detect from the drop-down menu to have Scream! attempt
to detect it for you. The instrument must be producing data for
this to work.
