I'm developing a test fixture for an embedded modem product and am having some problems breaking out of data mode. Here's the protocol in a nutshell:
Open COM port -> works Send "AT" -> works Look for "OK" -> works Send "AT&T1" -> works (enter internal loopback) Send "ABCD...." -> works Look for "ABCD...." -> works Send BREAK <1 second delay>"+++"<1 second delay> -> doesn't work Look for "OK" ....... For some reason, the modem is not breaking out and back into command mode. I verified the whole protocol using Hyperterminal. I've also created a button that just sends the BREAK and that works. I can tell that the modem is not seeing the BREAK by going back into Hyperterminal and sending the AT...which gets echo'ed back. That tells me it's still in loopback mode. By the way, the BREAK on my modem only requires about 300ms before and after. I'm using 1000ms for test purposes. Any ideas? Thanks, Scott Copeland Electronics, Inc.
