This is a typical buffer overflow problem when the plotter is driven serially. This occurs when the flow control is not properly set up for serial transmission. For serial data transmission most plotters are driven with the following parameters:
| Bits per second | 9600 | | Data bits | 8 | | Stop bits | 1 | | Parity | None | | Flow control | Hardware | You can change these values under Windows 3.x over program manager / main group / control panel / ports / COMx / settings and under Windows 95 over start / settings / control panel / system / device manager / ports (COM and LPT) / COM port (COMx) / port settings. If your plotter is set to other communication parameters, you can generally find the values in the display under the interface or communication menu and enter them in the Windows control panel.
