#777 is the CDMA standard number for "internet" access. There is also a
service option flag that determines how the IP is delivered so the
number is the same whether the access method is CSD aka QNC, 1xRTT or
EvDO. Many devices will "fall-back" to a slower technology if the faster
one fails to set up correctly.
If you dial 777 from your handset you should get a recording saying you
dialed an invalid number since the service option is set for a voice
call not a data call. If you connect your laptop, most phones will allow
you to use the phone as a modem. If you dial a phone number the call
will be delivered circuit switched, if you dial #777 the call will go
out with whatever service option is set in the phone (or via an AT dial
string).
HTH,
Jay

I am pretty sure my thing is EVDO now.
I didn't know "777" is the dial string.
Just looked up AT commands, ADTD is indeed the dial string command.
So, 777 is the data line for cell phones. 611 is their
station support line. I learned 777 from a page for sprint PCS.
So, both verizon and sprint use the same number.
I am tempted to dial 777 from my cell phone now. Don't know
whats going to happen. Wondering if they will give me a hi
pitch modem or fax like tone. Or if they will give me a
warning saying I am hacking them. I will just say I dial
it by mistake. Curiosity kills the cat.
