I assume that the only thing that could lead to such a behavior is some problem with the comm port.
The only switches that could make a difference is the "- Dsmslib.serial.polling" (which you already tried) and the "- Dsmslib.nocmti". All others should *not* have any effect at all for your problem. If possible, try to get another phone or modem to test for a couple of hours... On Sep 9, 4:21 pm, ravindra <[email protected]> wrote: > Hi, > > > like you.
