esp modem pppos_client example with Telit modem

[owenjames]

I am trying to establish a PPP connection to a Telit LE910Cx but the pppos_client example times out waiting for the IP address. The modem responds to the confg commands (AT+CGDCONT=1,"IP","internet" etc) although the config is minimal and there is no option for Telit modems. What puzzles me is that there is no evidence of support for the AT+CGACT command in the esp modem component but googling shows that this is required to establish a connection.
