Re: serial port: fconfigure -handshaking fails

Results in

bad option "-handshaking": should be one of -blocking, -buffering,
-buffersize, -encoding, -eofchar, or -translation

According to posts I've read here, this should work

Only if Tcl recognizes /dev/cuad0 as a serial port. If the ioctl() call
fails, you may get a misleading error message.

Maybe the driver on /dev/cuad0 does not support this specific ioctl() call?

Kind regards
