StampPlot assumes that
you will connecting on COM1 at 9600 baud (when using the Stamp's DEBUG
command, 9600 is the baud rate used). If COM1 will not be used,
use the Configuration button 
on StampPlot to change the port configuration.
- If you will always be using the same COM port (or
other port configurations), click Set as default to save this
configuration.
- Micro echoes data informs StampPlot that data sent to the
controller will be echoe'd back. In this case data sent to the
controller is suffixed with |Q| so returned data can be ignored.
(The BS2 echo's data on the programming port)
- Queue size is the amount of data to be held
awaiting processing. Should the number of bytes (characters)
exceed twice the queue size, StampPlot will disconnect.
- If DTR Enabled is selected, the BS2 will
reset whenever connection is made on StampPlot.
- Use RTS/CTS to control flow may be used to signal
the controller when StampPlot has at least 50 bytes (characters) in the
queue.
- RTS always on allows a constant signal back to the
controller to indicate StampPlot is connected or in special cases for
power to the controller.
- Changes on this tab will take effect next time you
connect.
Note:
Queue Size does not normally need to be changed unless
macro routines are extremely long or you are sending a large amount of
data for delayed processing (possibly logged data being dumped).

Control Instructions:
PORT baud, bits, parity,
stopbits, Queue Size,
DTR Enabled, RTS Enabled, RTS Always on
!PORT 19200,7,E,1,2000,0,1,0 |
See the Configuration window for
legal values.
DTR and RTS = 1 for enabled, 0 for disabled.
Allows the micro to configure the plot port. |
!QSIZ value
!QSIZ 5000 |
Sets the size of the queue. |
!ECHO ON/OFF
!ECHO OFF |
Enables micro echo. |
!SDTR ON/OFF
!SDTR ON |
Manually Set the DTR line. Set
after !CONN, ensure DTR enable is NOT selected in configuration or
it will reset to on.
|
!SRTS ON/OFF
!SRTS ON |
Manually set the RTS Line. Set
after !CONN.
|
!CONN ON/OFF
!CONN ON |
Open the serial (or TCP) connection |

Serial Problems:
 | Some BS2 serial configurations have problems communicating
to StampPlot.
By default, StampPlot is configured with DTR enabled (StampPlot Lite is configured
with DTR disabled). When DTR is enabled it will cause the BS2 to reset
and start any programs over. |
| On most BS2 boards, there are capacitors in series to the
BS2's ATN input to only allow a momentary change in DTR to reset to the BS2,
allowing the stamp to be reset. But some configurations may be lacking
a capacitor causing the BS2 to lock up. |
| Fixes:
 | Disable DTR in the configuration and save as default. |
| Or, insert capacitors in series with the DTR. |
