Differences From Artifact [9a9b1c960a]:

• File unix/gtkwin.c — part of check-in [d6cb32325e] at 2006-08-28 09:29:02 on branch trunk — Serial back end for Unix. Due to hardware limitations (no Linux box I own has both an X display and a working serial port) I have been unable to give this the full testing it deserves; I've managed to demonstrate the basic functionality of Unix Plink talking to a serial port, but I haven't been able to test the GTK front end. I have no reason to think it will fail, but I'll be more comfortable once somebody has actually tested it. (user: simon size: 106225)

To Artifact [26eb9a7d78]:

• File unix/gtkwin.c — part of check-in [8007266fdc] at 2006-09-03 09:31:34 on branch trunk — Support for an alternative mechanism for displaying wide characters under X: instead of having two separate fixed-width fonts one of which is twice the width of the other, you can instead have a single font in which some characters are twice as wide as others. This is implemented very simply: if you specify a wide font, it will be used for wide characters, and if you don't then the normal font will be used for wide characters (so they'd better _be_ wide in that font, or there'll be trouble). I got this idea from Jed, whose latest version supports UTF-8 and requires a font of this type. If there are going to be X fonts like that kicking around, there will doubtless be people who want to use them. (user: simon size: 106319)
