REMOVE ENABLE from FIFO buffers

This should help

Not all USB to serial adapters implement the full serial command set. The only one I've had great success with is from Keyspan. The USA-19 (19HS or 19Q or 19QW, whichever is current) works with every Mitsubishi, Siemens, Modicon, and Omron I have ever tried it with.

The ones from Belkin, IOgear, and Targus were intermittent at best, or worked with one device and not others.

Quatech SSP-100 G is a fairly reliable card that once inserted into laptop is flush with outside of laptop. Comes with an adaptor cable so you can leave it in laptop and not have to worry about it getting damaged unless you have the cable hooked up to it. I Also use the keyspan and I've had good luck with it.

Quatech only takes up one slot. It has a cable dongle. I can keep the card in there while traveling so I don't have to worry about damaging it. Haven't had a single miss with it yet, not saying its perfect though.
