Making USB using RS232 converter works really well with all the devices I tried.
USB to RS232 converter can also use FT8U232AM and Maxim-IC MAX235
If no FT8U232AM, could also use TTL level RS232 signals.
The FT8U232AM and supporting components are also available as a complete module – called USBMOD1 – in 32pin DIL IC packages, making the [...]

TTL RS232 driver circuit and Protect the PC from direct connection to hazardous voltages
TTL RS232 driver circuit.
TTL driver circuit consists of 2 transistors and a few other passive components, a negative voltage for RS232 logic generated by the capacitor C7.
TTL to RS232 driver circuit and a variable voltage output driver has a parallel termination impedance to match cable and TTL driver circuit, and provides the best waveform.
When driving [...]
