Hello there!

Is it possible to use the modem-emulation in a way that an application can fake-dial itsself into the internet, to establish a connection?
The application itself will connect to an IP adress after detecting a working dial-up connection.

From the guide about modem/IPX it seemed like it only supports 2 dosboxes to connect to each other, which wouldn't be applicable in my case.
regards

keen

Ehh..... You want something like this??

serial1=nullmoden telnet:nnn.nnn.nnn.nnn port:nnnn

where nnn.nnn.nnn.nnn is the IP-address to connect to, and nnnn is the port-number.

mmmh... The dialing would have originally been used to establish an internet connection to an ISP. Afterwards the applications use IPs "normally" to connect to something.
I wonder if there is a way to make the apps think they have established that connection to use their internet/ip functionality afterwards somehow.

Sounds like what you have is something that looks like this:

App <--> SL/IP (Serial Line IP Protocol) module <-> modem

and in the other end, there would be am ISP with

modem <-> SL/IP <-> Internet

That was a typical setup 20 years ago. Later SL/IP was replaced with PPP (Point-to-Point Protocol) which could do more that pass IP over a line.

that seems correct.

And after seeing/realizing that, I think I can forget about this....there is no "ISP" the app within dosbox could dial to (except another DOSbox waiting for a "call") and that "modem<->SL/IP<->Internet"-part cannot easily be replaced I guess. If I'm mistaken here, please correct me.
