#183201 - did You tryed capacitor?
Responding to: ???'s previous message
one possibility for cross-talk is to be "edge"- type,
maybe You can add:
- small capacitor on RX side of converter
- small resistor(about 0.5..1k) on TX side of converter
- both parts - near converter, not in DB9 on PC side

One cheap cable to try - network type, twisted pair - one pair for TX+GND,
second - for RX+GND.
