Hi, In my current redesign, I've also got rid of the telnet client. With my own comm-to-ip bridging interfaces, everything work ok. However, I think (it's a long time ago) that pure IP modems do require a telnet client. The good thing is that I have a Multitech IP modem lying around, so in the next days I will also try to connect to it with a straight socket.
(The other issue that's bugging me is that something has changed in Apache Commons v3 and smslib doesn't work any more with this... you have to use the old Commons version. So I will definitely throw away the telnet client if I can! On Sunday, April 8, 2012 9:41:25 PM UTC+3, wim stevens wrote: > > Hello, > > My modem is connected to a Ethernet-to-COM gateway.
