help, E220

[mistletoe]

My boss asked me to make a project. I bought a E220. But I can't
find the AT command reference.

oozie , can you send me this? Because I found you tested the
pyhumod project in E220.

My email:

mistle...@gmail.com

Thank you very much !

A very good AT commands reference page that I have been using is at:

Good luck with your project!

Hi oozie:
I found some questions about E220.
First, I have a RHEL4 virtual machine in Windows XP. When I
restart RHEL4 and the E220 is connected to RHEL4, the RHEL4 is
hanging. On the Google, i think the virtual cdrom in the E220 is the
suspect. Isn't that？

Second, I can't sometimes drive the E220.
