Chapter 1 BIOS and System Functions

The PT600 operating system supports DOS/BIOS function calls that a programmer

can access when developing an application for the portable.

1.1 Interrupt Vector Assignment for I/Os

Vector BIOS Function

09 H Display Font

0F H Kermit Server

10 H LCD Control

21 H System Functions

22 H Power Manager

31 H Beeper Control

33 H RS232 Control

1.2 Display Font Functions ( INT 09H )

00 Select Large Font

Entry Parameter: AH = 0/1 ; select 8*16-dot character font (4

lines * 16

; columns display)

Return Value: None

Example:

void TL_font(int status)

{

regs.h.ah = (unsigned char)status;

int86(0x09,&regs,&regs);

}

01 Select Small Font

Entry Parameter: AH = 1 ; select 6*8-dot character font (8 lines * 20

columns display)

Return Value: None

Example:

void TL_font(int status)

{

regs.h.ah = (unsigned char)status;

int86(0x09,&regs,&regs);

}

02 Set Font Type

3Entry Parameter: AH= 2

4AL= 0/1 ; set to large/small font

5Return Value: None

Example:

void TL_font(int status)

{

regs.h.ah = (unsigned char)status;

regs.h.al= 2;

int86(0x09,&regs,&regs);

}

03 Get Font Type

Entry Parameter: AH= 3

Return Value: AL= 0/1 ; large/small font

Example

int TL_get_font_type()

{

regs.h.ah = 3;

int86(0x09,&regs,&regs);

return(regs.h.al);

}

04 Set User-Defined Font for All Characters

Entry Parameter: AH= 4

AL= 0/1 ; large/small font

DS:DX ; pointer to the buffer with font data

; ( for large font: buffer size = 16*256 =4096

bytes

; for small font: buffer size = 6*256 =1536

bytes )

Return Value: None

Example

void TL_change_all_ASCII_font(int type,unsigned char *str)

{

regs.h.ah=4;

regs.h.al=(unsigned char)type;

segregs.ds = FP_SEG(str);

regs.x.dx = FP_OFF(str);

int86x(0x9,&regs,&regs,&segregs);

}

05 Get Font Data for All Characters

Entry Parameter: AH= 5

AL= 0/1 ; large/small font

DS:DX ; pointer to the buffer

; ( for large font: buffer size = 16*256 =4096

bytes

; for small font: buffer size = 6*256 =1536

bytes )

Return Value: Font data in the buffer

Example:

void TL_get_all_ASCII_font(int type,unsigned char *str)

{

regs.h.ah=5;

regs.h.al=(unsigned char)type;

segregs.ds = FP_SEG(str);

regs.x.dx = FP_OFF(str);

int86x(0x9,&regs,&regs,&segregs);

}

06 Set User-Defined Font for One Character

Entry Parameter: AH= 6

AL= 0/1 ; large/small font

CL =0 -255 ; character

DS:DX ; pointer to the buffer with font data

; ( for large font: buffer size = 16 bytes

; for small font: buffer size = 6 bytes )

6Return Value: None

Example:

void TL_change_one_ASCII_font(int type,int ascii_code,unsigned char

*str)

{

regs.h.ah=6;

regs.h.al=(unsigned char)type;

regs.h.cl=(unsigned char)ascii_code;

segregs.ds = FP_SEG(str);

regs.x.dx = FP_OFF(str);

int86x(0x9,&regs,&regs,&segregs);

}

07 Get Font Data for One Characters

Entry Parameter: AH= 7

AL= 0/1 ; large/small font

CL =0 -255 ; character

DS:DX ; pointer to the buffer

; ( for large font: buffer size = 16 bytes

; for small font: buffer size = 6 bytes )

Return Value: Font data in the buffer

Example:

void TL_get_one_ASCII_font(int type,int ascii_code,unsigned char *str)

{

regs.h.ah=7;

regs.h.al=(unsigned char)type;

regs.h.cl=(unsigned char)ascii_code;

segregs.ds = FP_SEG(str);

regs.x.dx = FP_OFF(str);

int86x(0x9,&regs,&regs,&segregs);

}

1.3 Kermit Server Function ( INT 0FH )

Entry Parameter: None

Return Value: None

When INT 0FH is called in user application, PT600 will enter Kermit server.

Pressing [CMD] key then [Exit] key to leave it and return to user application.

Example :

void TC_kermit_mode()

{

int86(0x0F,&regs,&regs);

}

1.4 LCD Control Functions ( INT 10H )

00 Clear LCD Screen

Entry Parameter: AH = 0

Return Value: None

Example:

void TL_clrscr()

{

regs.h.ah= 0;

int86(0x10,&regs,&regs);

}

01 Enable/Disable Screen Scroll

Entry Parameter: AH = 1

AL = 0/1 ; disable/enable screen scroll

Return Value: None

Example:

void TL_scroll(int status)

{

regs.h.ah = 1;

regs.h.al = (unsigned char)status;

int86(0x10,&regs,&regs);

}

02 Set Cursor Position

Entry Parameter: AH = 2

DH = Row

DL = Column PT6006x8 8x16

Row 0~7 0~3

Column

0~15 0~12

Return Value: None

Example :

void TL_gotoxy(int x,int y)

{

regs.h.ah = 2;

regs.h.dh = (unsigned char)y;

regs.h.dl = (unsigned char)x;

int86(0x10,&regs,&regs);

}

03 Get Cursor Position

Entry Parameter: AH = 3;

Return Value: DH = Row

DL = Column

Example :

void TL_getxy(int *x,int *y)

{

regs.h.ah = 3;

int86(0x10,&regs,&regs);

*y = regs.h.dh;

*x = regs.h.dl;

}

04 Display 16x16 Bitmap

Entry Parameter: AH = 4

DH = Row

DL = Column

DS:BX ; pointer to bitmap ( 32-bytes pattern data )

Return Value: None

Note: This function is available only in large font.

Example :

void TL_display_16x16_location(int x,int y,unsigned char *str)

{

regs.h.ah=4;

regs.h.dh=(unsigned char)y;

regs.h.dl=(unsigned char)x;

segregs.ds = FP_SEG(str);

regs.x.bx = FP_OFF(str);

int86x(0x10,&regs,&regs,&segregs);

}
