How can I invert the output to the data of a serial port after or while writing string data port? (e.g. ITA2 inverted TTY data)

ldjessup · ‎05-06-2002

I've converted ITA5 code to ITA2 and send it out the serial port (PC COM1) to a teletype (TTY). My next step is to provide the TTY with "inverted data". Not sure if I should convert the string data to binary and then invert, or is there a way I can invert the bits (levels) at the COM port? The latter is preferred.

Hi

unfortunately I don't have the preferred solution; but a working example for inverted byte. It does not invert the startbit & stopbit !!

Hi, i came over this topic when I did a search for TTY. I have an application that I am trying to automate the mas a manual step using MTTY to communicate over a serial port. Does anyone know if this can be replaced by all LabVIEW code or a call to other software? I would appreciate any help. Thanks.
