I have not seen the Huawei modems freeze up like this. Can you send
me the firmware version of the modem? I would like to compare it to the
ones I have here. This might be a windows driver or USB issue. Have
you had any debug output turned on when the freeze occurs? What is the
last output from the modem if you have?
The only issue I have seen on mine that make them go a little nuts is if
there are very large numbers of messages that go out. Wvery once in a
while my carrier will de-register my device and block it for a while.
Continuous sending for about an hour will usually cause that to occur.
I throttle sometimes to account for this.
One other thing that I remeber, and have a post somewhere about, is the
power requirements of the device is somewhat high. Make sure that the
USBport can supply the power and that if the computer has power
management features that it does not put the ports to sleep and hence
the modem. The modems don't like it.

Thanks Josh.I have been trying to use the modem with the smserver.java
program and it receives messages properly.The problem arised when i
have to send a message.When i queue it in the SMSSERVER_OUT database,
it tries to send it several times then eventually marks it as
failed.it also throws pdu error. ive resulted to using a nokia phone
modem for my outgoing messages since it accepts the text format. are u
using the smsserver? if so, how did you manage to send messages from
the E160?

We have been using this modem since January on a production system
that runs 24 hours a day, 7 days a week with SMSLib and it generally
works. We have noticed that once every few days the modem seems to
reset itself - it just stops responding to SMSLib. Most of the time
SMSLib restarts the modem and everything continues with no problems
but once every few weeks SMSLib is unable to reset the modem and we
have to stop and the program manually.
A couple of things to know about this modem:
You have to make sure to correctly specify the model and manufacturer
("Huawei" and "E160") when creating the modem in SMSLib so that SMSLib
uses the custom handler for this modem otherwise you will run into
strange intermittent problems.
This modem creates two virtual serial ports as has been described in
earlier posts. On a Windows system only one of the two ports will
show up in the device manager but both will show up if you enumerate
the ports using certain windows APIs. You should use the port that
shows up in the device manager rather than the other port. In our
experience this is always the higher numbered of the two ports. If
you use the other port, you will not get notifications for incoming
messages.
Good luck,
Josh

hi all,
has anyone been able to test the compatibility of the Huawei E160
modem? It is the only one i can find and would like to be sure whether
it works with the SMSserver program before purchasing it. thank you .
