 Almost all of USB to RS-232 adapters translate signals back to TTL and then they are sent over USB device. It is possible to bypass TTL <-> RS-232 translations by directly connecting USB-Serial adapter. There are plenty of them available and the ones with FTDI chip are proved to work with Tech 2. Almost all of USB to RS-232 adapters translate signals back to TTL and then they are sent over USB device.

 The procedure to connect a USB to UART module in the Tech 2 requires that you remove the existing serial transceiver chip (MAX202/​MAX232) completely. Then you need to attach the USB to UART module to the mainboard and solder some wires to correct pads in the mainboard. You might also want to remove the original serial connector (RJ45) to make some room for the USB to UART module. The procedure to connect a USB to UART module in the Tech 2 requires that you remove the existing serial transceiver chip (MAX202/​MAX232) completely.

 The module also seems to perform much better than the original RS232 connection. The original RS232 connection seemed to have reliability issues with higher baud rates but the USB-UART module works perfectly even with the highest baud rate (115200)! The module also seems to perform much better than the original RS232 connection.
