Changing RS-485 settings programmatically CVI

[Joncombat]

How can I change the RS-485 settings from 4 wire to 2-wire auto using CVI?

The ComSetEscape function provides support for some advanced functionality including the RS-485 transceiver mode.  Just call the function on your opened port and pass the value WIRE_2_AUTO.  Refer to the function help for more supported values.
