I'd definitely be interested in submitting a feature request. The use case is to enable inbound connectivity to a variety of DOS-based BBS applications that were built to answer calls on RS-232 modems. I have a high level sense that some portion of the AT command set has to be implemented, and that perhaps RS-232 signals/pins also have to be emulated. BBS's had to cope with a variety of modems that had various behavioral differences, but I don't have enough comprehension or knowledge to articulate the common or essential features to emulate. I think 95% compatibility with DOS-based BBS's would be a good target. It looks like tcpser would accept inbound tcp and provide modem emulation, but not provide a virtual serial device that could be exposed to dosemu2. It looks like socat would accept inbound tcp and link to a PTY, but not provide modem emulation and, perhaps, would not provide enough emulation of a serial device (RS-232 signals). tty0tty (https://github.com/lcgamboa/tty0tty) might fill i for serial emulation and enable tcpser -> tty0tty -> dosemu -> BBS, but I can't get the darn thing to install so far.
