<patch snipped>
Done. Below is the dmesg output with and without FLAGS=0x20000. You will
notice that, with the new patch, I no longer get the 'sio3: 65 events for
device with no tp' messages; unfortunately, however, the device still does
not work correctly. If I try to make a PPP connection to my ISP, the modem
dials, the chat proceeds (almost - see below) normally, but it seems to fail
to negotiate the PPP link. Here is a snippet of my ppp.log:
05-22 19:12:40 [155] sending: ATE1Q0
05-22 19:12:40 [155] Expecting OK-AT-OK
05-22 19:12:40 [155] Wait for (5): OK --> OK
05-22 19:12:40 [155] Chat: ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ
ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ
05-22 19:12:40 [155] Chat: OK
This string of 'ZZZZ's is abnormal. This connection attempt (and _all_
connection attempts with FLAGS=0x20000) failed.
