Support for Windows PuTTY connecting straight to a local serial port in place of making a network connection. This has involved a couple of minor infrastructure changes: - New dlg_label_change() function in the dialog.h interface, which alters the label on a control. Only used, at present, to switch the Host Name and Port boxes into Serial Line and Speed, which means that any platform not implementing serial connections (i.e. currently all but Windows) does not need to actually do anything in this function. Yet. - New small piece of infrastructure: cfg_launchable() determines whether a Config structure describes a session ready to be launched. This was previously determined by seeing if it had a non-empty host name, but it has to check the serial line as well so there's a centralised function for it. I haven't gone through all front ends and arranged for this function to be used everywhere it needs to be; so far I've only checked Windows. - Similarly, cfg_dest() returns the destination of a connection (host name or serial line) in a text format suitable for putting into messages such as `Unable to connect to %s'.

Name vtable structure types more consistently. Now they're all called FooVtable, instead of a mixture of that and Foo_vtable. 2018-10-05 06:03:46 +00:00			`const struct BackendVtable *const backends[] = {`
Rationalise access to, and content of, backends[] array. Should be no significant change in behaviour. (Well, entering usernames containing commas on Plink's command line will be a little harder now.) [originally from svn r7628] 2007-06-30 21:56:44 +00:00			`&telnet_backend,`
New GUI for protocol selection. This replaces the pure radio-button setup that we've always had on the Session config panel. Since the last release, that set of radio buttons has been getting out of hand. We've added two new protocols (SUPDUP, and the 'bare ssh-connection' aka psusan protocol), neither of which is mainstream enough to be a sensible thing to wave at all users on the front page of the config GUI, so that they perhaps start wondering if that's the protocol they want to use, or get sidetracked by going and looking it up. The replacement UI still has radio buttons, but only for the most common protocols, which will typically be SSH and serial. Everything else is relegated to a drop-down list sitting next to a third radio button labelled "Other". In every be_* module providing a backends[] list, there's also a variable n_ui_backends which indicates how many of the backends ought to appear as first-level radio buttons. (Credit where due: this patch is a joint effort between Jacob and me, and is one of those rare cases where it would be nice to be able to put both our names into the Author field of the commit. Failing that, I can at least mention it here.) 2021-04-10 08:51:29 +00:00			`&serial_backend,`

Add support for the SUPDUP protocol. Based on work by Josh Dersch, with permission. 2019-04-02 10:16:25 +00:00			`&supdup_backend,`
