It did help. I now have a (too much) reliable OnComm() event. I said too much, because it fire many times for each new string in the Input buffer.

I inserted a DEBUGOUT in the OnComm() event and it give me a series of "ATA" (when I ask the modem to answer the phone), a series of "CONNECT", etc. It doesn't give me problems for now, but I wonder why it fire so many times for a single event.

>Hi Sylvain. Does Message #257005 help?
