From 4a9624da0c7cf0c27a00e1ff497d13f2e4a0d03e Mon Sep 17 00:00:00 2001 From: Richard Qin Date: Tue, 10 Nov 2026 01:16:40 +0800 Subject: [mubios] Implement serial input and BIOS console key handling Implement UART receive, transmit timeouts, configuration and status reporting for INT 14h functions 00h-03h. Initialize the BDA serial timeout and expose the driver interfaces. Translate terminal characters and CSI/SS3 escape sequences into BIOS keyboard events for INT 16h. Add blocking reads, non-consuming status queries, enhanced key reads and keyboard buffer insertion. --- mubios/include/bios.h | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'mubios/include/bios.h') diff --git a/mubios/include/bios.h b/mubios/include/bios.h index 3c8b0dc..979e445 100644 --- a/mubios/include/bios.h +++ b/mubios/include/bios.h @@ -43,6 +43,12 @@ void bda_init (void); void serial_init (void); void serial_putc (u8 value); void serial_write (const char *text); +u16 serial_timer_counter (void); +u16 serial_status (u16 base); +u16 serial_configure (u16 base, u8 parameters); +u8 serial_transmit (u16 base, u8 value, u8 timeout); +u8 serial_receive (u16 base, u8 *value, u8 timeout); +int serial_try_receive (u16 base, u8 *value); u8 cmos_read8 (u8 index); -- cgit v1.2.3
