Subject: [OS2Wireless] USB 3G Modem

I have another opportunity to experiment with an external Huawei Turbo
3G USB Modem model E220. Per a Linux page on the net, this modem should
be configured using the AT-command set and then accessed using ppp.  I
have, per Lewis' earlier instructions, installed the USB-serial driver
but there does not seem to be any minimally functional terminal-program
part of eCS 1.2R and I don't have time to visit Hobbes and download any
terminal program today, it will have to wait until tomorrow.

In case there are any USB-experts in this forum, the USB Device Manager
identifies two devices plugged in: "SGS Thomson Microelectronics"
product 0x2016 and "4 Either Hand" product 0x1003.  The latter seems to
be the modem since it disappears when I unplug the USB cable.  Below I
have included the device report from the USB Device Manager for the USB
3G modem.

Comments from any knowledgeable persons are welcome before I visit
Hobbes to download a minimal terminal-program to explore further with. 
I can add that if I type 

echo "ATE0V1^SYSCFG=14,2,40000000,1,2" > com1

in a command window, the response is "the drive is not ready", trying
everything from com through com5 results in the same response while
com6 results in "the system cannot find the device specified," thus
there seems to be something on one of the COM-ports.  It is odd though,
that the report below talks about SCSI command set...
