Howdy, I use wininit.dll to check for a connection then to do dialup and later the hangup. I use internet exporer to access pages upload request and get back pages to parse.
**** examples below are snipped from active code [they work] to show the calls, the loops and returns are because they are in the middle of a bunch of other stuff and are part of functions and I did not clean it up much.

*connected state check
DECLARE Integer InternetGetConnectedState IN WinInet Integer @nContext, Integer nFlags
lnConnectionState = 0
fResult = InternetGetConnectedState(@lnConnectionState, 0)

*** to dialup on default ras
DECLARE Integer InternetDial IN WinInet Integer nHandle, String @lpcDialUp, Integer nAccessType, Integer @nConnect_Handle, Integer nFlags
** fResult = InternetDial(lnHWNDHandle, @lcDialUpName,nFlag,@lnConnectionID, 0)
fResult = InternetDial(0,"", 0, @nInet_Handle, 0)

***to open explorer access internet pages
If type('oie.document.url')<>'O'
Public OIE
OIE=createobject('internetexplorer.application')
Endif
OIE.navigate(cURL)
* rudimentary delay
=begwait("Loading Internet URL for Search . . . . ")
Do WHILE OIE.Readystate <> 4
Enddo
Do CASE
Case UPPE(OIE.document.title)=UPPE("Cannot find server")
Retu .f.
Case OIE.Offline
Retu .f.
Other
Retu .t.
Endcase
**** to utilize asp page, you must know page objects names
OIE.document.form_1.vin_1.value=cVIN
OIE.document.form_1.submit

Enddo
ctext=OIE.document.body.innertext

Retu ctext
*** to logout etc
