The currently used backlog of (1) effectively disables any two or more simultanueously incoming connections at the kernel level, because the backlog parameter only allows 1 such connection. Yet since terminal multiplexers can handle tens of clients, it's not technically impossible to have more than one incoming request to be received at any particular moment (for two different "lines"). A reasonable backlog of more than 1 safeguards that the "extra" connections won't be refused outright, and postpones that decision to be made by simh (not the kernel) -- for example, when, say, all multiplexer lines are busy, with an explanation (which states so) rather than just the infamous "Connection reset by peer" (effected by the kernel reset). This patch increases the backlog to 64.
Open SIMH machine simulator
This is the codebase of SIMH, a framework and collection of computer system simulators.
SIMH was created by Bob Supnik, originally at Digital Equipment Corporation, and extended by contributions of many other people. It is now an open source project, licensed under an MIT open source license (see LICENSE.txt for the specific wording). The project gatekeepers are the members of the SIMH Steering Group. We welcome and encourage contributions from all. Contributions will be covered by the project license.
The Open SIMH code base was taken from a code base maintained by Mark Pizzolato as of 12 May 2022. From that point onward there is no connection between that source and the Open SIMH code base. A detailed listing of features as of that point may be found in SIMH-V4-status.
