Terminal ID
Entry Parameter: AH = 1DH
BH = 0
DS:DX ; pointer to buffer of 8 characters ID string
Return Value: None
Example :
void TT_id(unsigned char *str)
{
segregs.ds = FP_SEG(str);
regs.x.dx = FP_OFF(str);
regs.h.ah=0x1D;
regs.h.bh=0;
int86x(0x21,&regs,&regs,&segregs);
return(regs.h.al);
}
1.5.14.2 Set ONLINE/LOCAL in Terminal Mode
Entry Parameter: AH = 1DH
BH = 1
AL = 0/1 ; ONLINE/LOCAL
Return Value: None
Example :
void TT_online_local(int status)
{
regs.h.ah=0x1D;
regs.h.bh=1;
regs.h.al=(unsigned char)status;
int86x(0x21,&regs,&regs,&segregs);
}
1.5.14.3 Set ECHO ON/OFF in Terminal Mode
Entry Parameter: AH = 1DH
BH = 2

Example :
void TT_echo(int status)
{
regs.h.ah=0x1D;
regs.h.bh=2;
regs.h.al=(unsigned char)status;
int86x(0x21,&regs,&regs,&segregs);
