On windows xp, using the "shared serial ports 2.0" trial, I have tried to share the com port connected to a hsdpa/gsm modem, so that I could use windows dial-up networking along with a program for sending sms messages.
When sharing the com-port, windows dial-up just reports that the com-port is already in use ( by serial ports sharing, I guess ).
When un-sharing the port, DUN works fine.
I thought it might be because the dial-up connection can't get hold of the control signals, but what program should I assign control to? rasdial?
Have I missed a point about this software? Any suggestions?
