Hi hard to say what the problem is but _) Verify that your modem is not storing messages in its internal buffer _) Your modem migh freeze because of too many stored messages _) If you decrease the throughput thoughput=10, still having the same problem? _) Check with minicom or other terminal sw of you can connect to the modem and verify memory status. _) Some modems use the same memory allocations for MT & MO... might you have MO stored in your modem? _) Set logs to debug to see if you get more info
