I've finally handled SIM code entering in the network::mobile_data module, using non-blocking IO and the IO::Select module. It's tricky to parse gcom output since no newline character is written after the "enter SIM code" message... So, the new network tool is now able to fully initialize 3G/Edge/GPRS cards managed by gcom, and to list networks.

Another 3G/Edge/GPRS requirement is to run AT commands to establish the connection, but they're specific to the card. The new network tool should be able to write the right AT commands in a chat script when a card is selected.

This GUI has also a new generic way of displaying networks, that I implemented for 3G first, barely based on drakroam. The nice thing is that once it's done for a connection type, we get it for free (well, 2 lines of Perl actually) for other connection types (for example wireless).

It also handles static lists of providers, they are displayed in a treeview the way the drakconnect does. Same thing, once it's done for xDSL, the POTS providers are supported some minutes later.

Yet, the new interface allows to select devices, initialize them, list networks if possible, select a provider if possible. I just have link that to the actual connection tools, asking authentication parameters first if needed.
