My GV x2 modem comes with a fairly long and complex script for use with the
MacOS. When I was having problems similar to what you describe (intermittent
though, not all the time) I took a look at the script (how is another story. . .
) and I discovered that when the modem is not responding DTR is toggled off then
on. I think this is what is needed with the intermittent problem that I am
having, but I haven't figured out how to do this in Linux. For now when it
happens I have to reboot MacOS, dial the modem to get things working, then reboot
Linux. Another thing that may be going on in your case is that the display
result code option may be disabled so the modem is not signaling "OK" to any of
the computer's commands. In my modem this is enabled by "ATQ0". Kppp has a
window you can use to communicate with the modem directly. My modem responds
with a list of commands it responds to if you type "AT$".
