PHS8 Terminal and Dialup using RS232 serial port | Telit Cinterion IoT Developer Community

January 28, 2020 - 2:54pm, 2323 views

Hello,

I try to make a Dialup using the PHS8T modem terminal and a laptop with Windows 7 / 64 bits.

First I connect USB modem port to the laptop, then I install the driver: Cinterion PH8 USB CDC-ACM Modem. Setup a Dialup connection and I can connect to the Internet.

After that I try to make a Dialup connection using RS232 serial port (ASC0). I use AT^SDPORT=2 to make modem interface available on ASC0. Then I connect the ASC0 modem port to the laptop and install the driver: Standard 9600 bps modem driver. In this case Dialup connection do not work ok. Modem is register on the network but the  data transfer are not available. 

The ASC0 port and USB port it should not behave the same?

Have you any ideea or sugestion?

Best Regards,

Ionel
