Why should uncommenting -3- help when it happens *after* the hGetLine?

It doesn't. It helps if going before. My fault. I pasted to the msg somehow edited code, so the additional lines and comments was not checked.

Is your Tcl-app printing out "click" or "click\n", i.e. with the additional linefeed?

Command 'puts "click"' makes implicit line brake, so yes, "click\n"

Did you try disabling blocking entirely?

I tried. No effect, as expected. Max.
