; ; BIOS Macros ; ; These macros define the indeterfaces to the BIOS. These macros aid in ; making calls to BIOS from other assembly language routines. These macros ; provide the complete interface to the particular BIOS function. ; ; ; LDREG ; ; This macro is an "inner" macro for the use by the BIOS interface macros. ; It allows the caller of a macro to specify a register or a literal value as ; the parameter to the macro. This macro loads the correct register specified ; by the caller of the macro with the contents of the register, literal or ; memory location also specified. No code will be generated if the two ; parameters are the same. ; ldreg macro destreg,source ifdif <destreg>,<source> mov destreg,source endif endm ; ; TSTNSET ; ; This macro will compare the value of two fields, if they are equal the ; third parameter will be OR'd into AL. ; tstnset macro src1,src2,orval ifidn <src1>,<src2> or al,orval endif endm ; ; IRS232 ; ; This macro will generate a call to BIOS to initialize the RS232 port. ; irs232 macro initparms,linenum ldreg dx,linenum ldreg al,initparms mov ah,0 int 14h endm ; ; IRS232A ; ; This macro will generate a call to BIOS to initialize the RS232 port. ; This macro allows the fields to be specified that initialize the port. ; irs232a macro baudrate,parity,stopbits,datalen,linenum ldreg dx,linenum sub ax,ax ; tstnset baudrate,110,00000000b tstnset baudrate,150,00100000b tstnset baudrate,300,01000000b tstnset baudrate,600,01100000b tstnset baudrate,1200,10000000b tstnset baudrate,2400,10100000b tstnset baudrate,4800,11000000b tstnset baudrate,9600,11100000b ; tstnset parity,none,00000000b tstnset parity,odd,00001000b tstnset parity,even,00011000b ; tstnset stopbits,1,00000000b tstnset stopbits,2,00000100b tstnset datalen,7,00000010b tstnset datalen,8,00000011b int 14h endm ; ; SENDCHR ; ; This macro will send a character over the RS232 line. ; sendchr macro char,linenum ldreg dx,linenum ldreg al,char mov ah,1 int 14h endm ; ; RECVCHR ; ; This macro will recieve a character from the RS232 line. ; recvchr macro linenum ldreg dx,linenum mov ah,2 int 14h endm ; ; COMSTAT ; ; This macro will get the status of the RS232 line. ; comstat macro linenum ldreg dx,linenum mov ah,3 int 14h endm ; ; GETKBCHAR ; ; This macro will get a character from the keyboard. ; getkbchar macro mov ah,0 int 16h endm ; ; TSTKBCHAR ; ; This macro will test to see if a character is available from the keybd. ; tstkbchar macro mov ah,1 int 16h endm ; ; GETKBSHIFT ; ; This macro will get the keyboard shift state. ; getkbshift macro mov ah,2 int 16h endm ; ; DSKRESET ; ; This macro will reset the diskette controller. ; dskreset macro mov ah,0 int 16h endm ; ; GETDSKSTAT ; ; This macro will get the diskette status of the last operation performed. ; getdskstat macro mov ah,1 int 16h endm ; ; DSKREAD ; ; This macro will read from the diskette. ; dskread macro drive,head,track,sector,numsecs,buffoff ldreg dl,drive ldreg dh,head ldreg ch,track ldreg cl,sector ldreg al,numsecs ldreg bx,buffoff mov ah,2 int 16h endm ; ; DSKWRITE ; ; This macro will write to the diskette. ; dskwrite macro drive,head,track,sector,numsecs,buffoff ldreg dl,drive ldreg dh,head ldreg ch,track ldreg cl,sector ldreg al,numsecs ldreg bx,buffoff mov ah,3 int 16h endm ; ; DSKVERFY ; ; This macro will verify the diskette. ; dskverfy macro drive,head,track,sector,numsecs,buffoff ldreg dl,drive ldreg dh,head ldreg ch,track ldreg cl,sector ldreg al,numsecs ldreg bx,buffoff mov ah,4 int 16h endm ; ; DSKFORMAT ; ; This macro will format the diskette. ; dskformat macro drive,head,track,sector,numsecs,buffoff ldreg dl,drive ldreg dh,head ldreg ch,track ldreg cl,sector ldreg al,numsecs ldreg bx,buffoff mov ah,5 int 16h endm ; ; PRNTCHAR ; ; This macro will print a character on the printer. ; prntchar macro char,printer ldreg al,char ldreg dx,printer mov ah,0 int 17h endm ; ; INIPRNTR ; ; This macro will initialize the printer. ; iniprntr macro printer ldreg dx,printer mov ah,1 int 17h endm ; ; PRNTSTAT ; ; This macro will get the printer status. ; prntstat macro printer ldreg dx,printer mov ah,2 int 17h endm ; ; SETCRTMODE ; ; This macro will set the vidio mode for the CRT. ; setcrtmode macro modeval ldreg al,modeval mov ah,0 int 10h endm ; ; SCRTMODE ; ; This macro will set the vidio mode for the CRT.
