[RESOLVED] Help with PCMCIA modem and a cellular phone

Hi, I have a USR KJ5560 PCMCIA card modem attached to a Startac 6500 cellular phone. I try to use it with my TI Extensa 610CD notebook in order to send faxes and scanned photographs from any place to my office.

The problem is that, the fax works well but I just can't get a continous communication between the notebook and my office's computer.

The modem starts to dial and even onnects with the desktop, but when I try to do something or try to transfer files, the modem disconnets the thransmission. Can anyboby help me?

Thanks
