If all you want to do is get rid of the tcl error, add a catch statement:

Code:

proc radio:dataget { hand idx text } {    global lynx radio    set rfs "[open $radio(file) w]"    if {[catch {exec $lynx -preparsed -dump http://www.xxxx.com:$radio(port)} result]} {        putlog "error"    } else {        puts $rfs $result    }    close $rfs    return 0}

Maybe instead of putlog "error", you want to put a default message into that file, indicating that the site could not be contacted.

Use the likes of the Tcl HTTP package.

You have full control over how errors return then.

Hello,

i have this command in my code: exec $lynx -preparsed -dump $radio(host)

if $radio(host) is down, lynx returns an error:
[18:26] Tcl error [radio:dataget]:
Looking up www.xxxx.com
Unable to locate remote host www.xxxx.com.
Alert!: Unable to connect to remote host.
lynx: Can't access startfile http://www.xxxx.com

how could I check if the host is up or not, so if it's down this procedure do not return a error?

thx
