We bought the FTDI adapter as suggested, updated the driver for the prolific as suggested, tried to switch to Microsoft USB to Serial, only to blue screen the machine. We put a serial port sniffer on the machine and can see the data getting transmitted to the device, an Epson TM-U375 serial printer that we use all over the place.

For most of these operating systems two types of driver are available: Virtual COM Port (VCP) drivers and direct (D2XX) drivers. The VCP driver emulates a standard PC serial port such that the USB device may be communicated with as a standard RS232 device. The D2XX driver allows direct access to a USB device via a DLL interface.

[PC] ----- USB cable -------- [FTDI FT230X USB-UART device][TX, RX, RTS signals]
Issue1: Whenever an FT230X device is connected or powered up and Windows scans for USB devices, the RTS line is toggled
Issue2: Whenever the FT230X RTS line is toggled using RTSenable, the TX line (if low using BreakState) toggles high.
Issue2: Whenever the FT230X RTS line is toggled using RTSenable, the TX line (if low using BreakState) toggles high.
Code Example:
SerialPort1.BreakState = True ' Rx low (sets Rx line low)
SerialPort1.RtsEnable = True ' RTS low (sets RTS line low AND Rx high)
SerialPort1.RtsEnable = False ' RTS high (setsRTS line high)
SerialPort1.BreakState = False ' Rx high (this has no effect since Rx is already high) Seagate external hard drive drivers free download.
SerialPort1.RtsEnable = True ' RTS low (sets RTS line low AND Rx high)
SerialPort1.RtsEnable = False ' RTS high (setsRTS line high)
SerialPort1.BreakState = False ' Rx high (this has no effect since Rx is already high) Seagate external hard drive drivers free download.
Toggling RTS should have no effect on the TX line. The issue only occurs with the FT230X chip. The same VB code running a PICkit Serial module works properly i.e. toggling RTS has no effect on TX.
Has anyone else seen this issue before, can duplicate it or shed some light on the issue?

Future Technology Devices International, commonly known by its acronym FTDI, is a Scottish privately held semiconductor device company, specializing in Universal Serial Bus (USB) technology.[1]
It develops, manufactures, and supports devices and their related software drivers for converting RS-232 or TTLserial transmissions to USB signals, in order to allow support for legacy devices with modern computers.[2]
FTDI provides application-specific integrated circuit (ASIC) design services. They also provide consultancy services for product design, specifically in the realm of electronic devices.

FTDI was founded on 13 March 1992 by its current CEO Fred Dart. The company is an indirect descendant of Computer Design Concepts Ltd, a former semiconductor technology startup, founded by Dart.

FTDI's initial products were chipsets for personal computer motherboards, the primary customer of which was IBM, which used them in its AMBRA and PS/1 personal computers. It later expanded its product line to include interface translators, such as the MM232R and the USB-COM232-PLUS1, along with other devices for converting between USB and other communication protocols.
Currently, the headquarters for FTDI is located in Glasgow, Scotland, United Kingdom, while it also has offices in Singapore, Taipei, Taiwan, and Portland, Oregon. The company's manufacturing division is handled by subcontractors in the Asia Pacific region.
Driver controversy[edit]
On 29 September 2014, FTDI released an updated version of their USB-to-Serial driver for Windows on their website. [3] Users who manually downloaded the new drivers reported problems.[4] After Windows drivers became available on 14 October (Patch Tuesday) via Windows Update, it was reported by users of hardware enthusiast forums and websites that the drivers could soft-brickcounterfeit and software-compatible clones of the chips by changing their USB 'Product ID' to '0000'. The change prevents the chip from being recognized by drivers of any OS, effectively making them inoperable unless the product ID is changed back.[5] The behaviour was supported by a notice in the drivers' end user license agreement, which warned that use of the drivers with non-genuine FTDI products would 'irretrievably damage' them.[5] Critics felt that FTDI's actions were unethical, considering that users may be unaware that their chips were counterfeit, or that Windows had automatically installed a driver meant to disable them.[6][5][4][7] On 22 October 2014, an emergency patch was made to the FTDI drivers in the Linux kernel to recognize devices with the '0000' ID.[8]
On 24 October 2014, in response to the criticism, FTDI withdrew the driver and admitted that the measure was intended to protect its intellectual property and encourage users to purchase genuine FTDI products. The company also stated that it was working to create an updated driver which would notify users of non-genuine FTDI products in a 'non-invasive' manner.[9][6]
In February 2016, it was reported that FTDI had published another driver on Windows Update with DRM components intended to block non-genuine products. This time, the driver will communicate with affected devices, but all transmitted and received data is replaced with the arbitrary, looped ASCII string 'NON GENUINE DEVICE FOUND!', which could cause irregular interactions with devices.[10][11]
