Hi,
I’ve had problems with the Cloverleaf Tcl install trying to run scripts I’d written using a full Tcl install. Although the bulk of the files/libraries are installed some of the specialist one’s appear to be missing. It could be that the low level TCP/IP library is not installed.
I haven’t tried this so can’t confirm it but if everything else in your script is correct then this is what the error suggests to me.
Regards
Garry
