waiting on tcp ports

Hi all, I have a problem. I execute this code: port1: open/lines/direct tcp://:4321 port2: open/lines/direct tcp://:8989 data: make string! 1000 ready: wait/all [port1 port2 10] if ready [ probe read-io ready data 1000 ] to listen on multiple ports. I observe the following error: ** Script Error: read-io expected port argument of type: port ** Near: probe read-io ready data 1000 How can I read the data when listening on two or more ports? (the same error with dispatch) Thanx, Miguel Lopez

You are assuming ready is one of the two ports, however, wait can return none! (when you get a 10 second timeout). So check that ready is really a port, like this: if port? ready [ ... ] Anton.

Hi Miguel, On Saturday, May 22, 2004, 4:40:17 PM, you wrote: ML> ready: wait/all [port1 port2 10] Since you are using /ALL, READY can be a block with both ports in it. So either you should remove the /ALL refinement (so that at most one port will be returned each time), of you should read from all ports returned. BTW, I'd recommend not using READ-IO unless really necessary (that is, unless you are using async-modes). Use COPY instead.
