Latest update breaks modem #2

Closed troykrahn closed 4 years ago

troykrahn commented 4 years ago

With the latest update I can no longer get my modem to initialize, any attempt to run mm_manager fails with Error Initializing Modem

Modem

My modem is a Multitech Systems MultiModem2 (model MT5600). I've looked inside this modem and it does appear to have a Conexant chipset.

Operating System

I am running a Debian based Linux system.

Steps to Reproduce

  1. Power on modem
  2. Run ./mm_manager -m -n 18005551234 -f /dev/ttyX -l install.txt
  3. mm_manager seems to reset the modem, but fails afterwards

Troubleshooting Performed

I have tried restarting the modem and resetting it manually, but neither seem to make any difference.

Check the last commit to mm_modem.c, I changed the baud rate from 19200 to 1200. Can you please try changing it back? I will add a command line parameter for it.

troykrahn commented 4 years ago

I've changed the speed back to 19200 but the issue prevails. I'm wondering if there's something different about my modem that just makes it difficult to interface with.

hharte commented 4 years ago

I ordered the MT5600, will give it a try when I receive it.
