From 2533eca1c2b9d561c42d28bcb6f1c1c35562fbcc Mon Sep 17 00:00:00 2001 From: Warner Losh Date: Wed, 3 Nov 2021 15:55:42 -0600 Subject: [PATCH] vt(4): Connect to teken's TP_SETBELLPD Add the glue needed to listen to TP_SETBELLPD which teken uses to inform its client drivers about the results of parsing \e[=;B. It converts these to a Hz value for the tone/pitch of the bell and a duration in ms. There's some loss of precision because in the escape seuquence is defined to be (1193182 / pitch) Hz and is in 10ms units. Also note that kbdcontrol also parses 'off' but then doesn't send the proper escape sequence, leading me to wonder if that's another bug since teken appears to parse that sequence properly and I've added code here to treat that as the same as quiet or disabled. In general, Hz from 100 to 2000 is good. Outside that range is possible, but even at 100Hz the square wave is starting to sound bad and above 2000Hz the speaker may not respond.
