In their examples, they set the handshaking to RTS/DTR which means ( I believe) that All 4 pins (DTR/DTS and RTS/CTS) need to be active. If so, then pulling the plug will stop the flow. Since that produces the same symptoms, it is logical to assume that either the LCD or Win is dropping a signal. If you want to ignore errors, turn off all flow control (if Win will let you).
