This seems to work fine on the current SVN version. 

Will recheck on SRV-1.

Thanks for looking into this.

Another test result:

Perhaps there is a memory usage problem: one thing stepping on another?

CC##Xmodem success. Count: 768

void PDQ(int v, int d, int h)
{
        printf("%d, %d, %d\r\n", v, d, h);

int u;

PDQ(0,       0,     0x0);

u=15;
PDQ(u,      15,    0x0F);
PDQ(u+1,    16,    0x10);

Hi, Howard has recent found a problem with the memcpy() function on the SRV-1.
Updating to his new memcpy() may solve your memory corruption problem. I'd be
interested to know if you have any success with this.

Calling this one closed unless I hear otherwise.
