title: Can you emulate a null modem mode in CH341 driver?
body: <p>I've installed a device in a remote location with a serial to USB converter connected to a Raspberry Pi. Due to a series of unfortunate events, it turns out that the instrument should have been connected with a null modem cable and now the Tx and Rx of the RS232 DB9 is the wrong way around.</p>
  <p>Is there any way for the Tx and Rx to be swapped in software by changing the driver source? I have been able to build and install the driver module manually, just need to know if and how the CH341 can be configured. (I've seen that some other drivers have a &quot;null modem&quot; configurable block).</p>
