Summary:
The Microsoft C Compiler version 6.0 will hang when the sample program
below is compiled default or any other optimization for any memory
model:
Using the quick compile (/qc) option will allow the program to
compile.
Microsoft has confirmed this to be a problem in C version 6.0. This
problem was corrected in C version 6.0a.

/* Compile options needed: none
*/
#define LCPPORT 0
#define COMREQ 0x14
#define FOREVER for(;;)
extern void _far _cdecl delay(int ticks);
void clrlcp(void)
{
int ticks = 4;
FOREVER
{
_asm
{
push [ticks]
call delay
add sp,2
mov dx,LCPPORT
mov ah,7
int COMREQ
cmp al,0
jz done
mov dx,LCPPORT
mov ah,6
int COMREQ
}
ticks = 4;
}
done: return;
