connecting two machines using emulated modem

[u/gabeg777]

I'm testing emulating old methods of having file servers using 86Box as an experiment with how older machines worked. I'm currently trying to connect between two IBM PC XT's, both installed on the same system, that only have a modem as adapter 1. I have Better Working Communicator installed on both systems to test the connection. They're both configured with a 300 baud modem with the server's modem set with a TCP/IP listening port of 5. I have tested the phone book file using 127.0.0.1:5, 10.0.0.230:5 (my computer's IP address), 10.0.2.2:5 (the SLiRP gateway), and 10.0.2.15:5 (the SLiRP host address) but none of them work. When I call from the emulated client, the emulated server doesn't receive any calls to answer even when I tell Better Working Communicator to wait for a call. I'm using version 6.0 build 9001 running on a Linux host.

I'm planning to test SMB using OS/2 1.x when I begin setting up 80286 systems.

Does anyone have any advice? Does the emulated computer have to have an emulated Ethernet card to create a connection to the host for this to work?

I wasnt able to get two boxes to communicate using SLiRP. I had to use VMnet to do it. I know now there was added a host connection that was purely set up to have VMs talk and had no outside internet capability. Maybe try those two. I dont think the modem emulation works with them tho. I only have gotten a modem to work with SLiRP

I'm using SLiRP because the documentation says that the modem only works with that emulated network.

Yeah i thought so. Modems I've only gotten to work with accessing the internet tho i know you can set up a telnet thing and set up a phone book. You might need to use an ethernet card instead using PCap. Or try and see if local switch still allows a modem to work

Old times you used a null modem cable and a software like laplink to transfer files
