Transfer -> Send Text File

I've used it many times (with HW serial port, FTDI adapter and RP2040), and there have been no (wrong) data problems with it (or at least I can't remember any, and I've sent raw binary files like an ELF). I am not entirely sure though, maybe I used "Viewdata" terminal type for sending in some cases too. No change to the sending speed from that though.

On receiving (Transfer -> Capture Text), it does tend to skip characters or change them when non-text characters are received (like backspace), in which case the workaround is to change the terminal type to "Viewdata".

I've also used it with HW flow control, transferring at 115200bps (and flow control was needed because the MCU I used couldn't keep-up with the incoming data). I am not sure if that was with an RS232 port or FTDI adapter.
