Hi guys! Im building an application where I want to be able to have 3 USB UMTS modems in one computer.

Does anyone have experience in using several modems at the same time?
I also want them to be able to be up and runninng at the same time,each connected to a different network through VPN tunnels.

So far, I have connected two Option Globetrotter Mini PCI Express cards with USB cradles (this is the option embedded development kit)
But I can use any modem, I also have two Option Globesurfer ICON that I can try If I need to, and I have PCCARD Globetrotters aswell.

If I have two USB modems they register as two seperate devices, the first getting usbtty0 to 3 and the second usbtty4-7

I use OpenSuse 10.3

do you think that will be any problems in calling with two or three modems at the same time?

Do I need to use PPP dial or can I get them to turn up like network interfaces so I can see them in IFCONFIG?

Thankfull for any advice Wink

Just make for every modem one call script and run them with pppd, then you will have ppp0, ppp1 and ppp2. just check that you will have the correcte routes for every network!

can you tell me, if this is the option card that you are using:
