#190220 - COM Port handshaking with DB9-USB converter module

Flash Magic can be used to control the ISP mode by using COM port handshaking devices by automatically place into ISP mode and then automatically will execute the code at the end of the writing operation. The microcontroller used is P89C51RD2HBA and this operation was successfully done using the DB9 RS232 connector. However, now, i want to use the DB9-USB converter module from FTDI where all the pins were identical.

The ISP mode can be controlled at first but, Now, the problem I'm facing was once it enter the ISP mode and execute the code,
it cannot enter the ISP mode anymore. Does FTDI converter module support the COM Port handshaking operation?

Any help highly appreciated.
