⚙️ OCX Dependencies - NONE REQUIRED!

IMPORTANT: This .NET version requires ZERO OCX files or COM components!

What Were OCX Files?

The original VB6 version used:

MSComm32.ocx - Serial communication (replaced by System.IO.Ports)
MTMicrImage.ocx - MICR image processing (replaced by custom ImageProcessor)
ComDlg32.ocx - Common dialogs (replaced by .NET Windows Forms)

Modern .NET Replacements

Legacy OCX	.NET Replacement	Benefits
MSComm32.ocx	`System.IO.Ports.SerialPort`	Native .NET, better error handling
MTMicrImage.ocx	`ImageProcessor.cs`	Custom implementation, full control
ComDlg32.ocx	`System.Windows.Forms`	Built-in .NET controls

Advantages of No OCX Dependencies

✅ No COM Registration: No regsvr32 required
✅ No Version Conflicts: No DLL hell issues
✅ Cross-Platform Ready: Can run on Linux/macOS (with hardware limitations)
✅ Deployment Simple: Single executable with zero external dependencies
✅ Security: No external COM components to maintain

{
    // Device status check
    return SendCommand("STATUS\r");
}

🚨 Troubleshooting

Serial Port Connection Issues

Windows Troubleshooting

Port Detection: Use Device Manager to verify COM port assignment
Port Conflicts: Ensure no other applications are using the same COM port
Driver Issues: Update/reinstall USB-to-serial drivers
Cable Problems: Test with known working cable and scanner
Power Issues: Ensure MICR scanner has proper power supply
Baud Rate: Try different baud rates (9600, 19200, 38400)
USB Naming: Use USB1, USB2, etc. for user-friendly port selection

Linux Troubleshooting

Port Permissions: sudo usermod -a -G dialout $USER then logout/login
Port Detection: Check /dev/ttyUSB* or /dev/ttyACM* devices
Driver Issues: Install appropriate USB serial drivers
Permission Denied: sudo chmod 666 /dev/ttyUSB0 (temporary fix)
Device Recognition: lsusb to verify USB device detection
Port Naming: Use full device paths like /dev/ttyUSB0 or user-friendly names

Connection Testing

Windows: Use PuTTY or HyperTerminal to test serial communication
Linux: Use minicom or screen /dev/ttyUSB0 9600 for testing
Loopback Test: Connect TX to RX pins to test port functionality

Common Error Messages

"Access denied": Permission issues (run as admin/sudo)
"Port not found": Wrong COM port or device not connected
"Timeout": Baud rate mismatch or device not responding
"Device not ready": Hardware power or initialization issues

Permission Issues

Windows: Run as administrator if access is denied
Linux: Add user to dialout group for serial port access
Antivirus: Check if security software is blocking serial communication
File System: Verify user has write permissions for output directory

Testing Issues

Use virtual serial ports (like com0com) for development
Check test output for detailed error messages
Run tests individually to isolate issues

Logging

Check GetImageNet.log for detailed error information
Enable debug logging in App.config for verbose output
Logs include timestamps and full stack traces
