Turns out that echo is enabled by default after ATZ, but ATE=1 behaves very strangely on my modem. It actually turns off echo and sets S0=1. This is true with two different firmware revisions as well. I removed ATE=1 from the init, and now I get much further into the process (though it is currently still failing with CRC errors, they are now different each time).
Hello, I'm trying to get this to work with a USR 5637, and firmware NPA1F01.
First issue I have is that the init string doesn't seem to get applied properly. I know this because using the proposed init string
ATE=1 S0=4 S7=3 &D2 +MS=Bell212A
, the modem never answers. If instead after mm_manager is launched, I connect using screen and set these settings manually the modem behaves as expected.However, even when the modem is seemingly initialized properly after manual intervention, I am stuck with the following error.
I've tried adding
B1
,&N2
, andM0
to the init, all to no avail. I always get the exact same result.Attached the resulting log (the pcap is empty): mm_manager.log.
