------------------ Additional Follow-up Comments ----------------------------
I'm sorry but the code was a little confusing due to mix of integer and hex 
presentation. The correct test code is:

-----------------

    for (i=0;i<(int)sizeof(EnterPgmMode_Reply);i++) {

      printf("%x: %x = %xn", i, buf[i], EnterPgmMode_Reply[i]);

-----------------

and the printout is:

-----------------

prompt>/uisp -dprog=stk500 -dserial=/dev/ttyS0 -dpart=AT90S8515 --erase 
--upload --verify if=rom.hex

Firmware Version: 1.14

0: 14 = 14

1: 11 = 10

Failed to enter programming mode.

I'm sorry, hope I havent confused you to much.

Summary:  uisp fails to enter programming mode on STK500

Original Submission:  When trying to program STK500 with the latest version of 
uisp (version 20030618) it fails to enter programming mode. I have compiled in 
some printf's to try to track what is failing and this is what it says:

------------------

prompt>uisp --version

uisp version 20030618

--------------------------------------

prompt> uisp -dprog=stk500 -dserial=/dev/ttyS0 -dpart=AT90S8515 --erase 
--upload --verify if=rom.hex

Firmware Version: 1.14

0: 14 = 20

1: 11 = 16

Failed to enter programming mode.

prompt>

--------------------------------------



The code I changed is in Stk500.C:

---------------------------------------

void TStk500::EnterProgrammingMode() {

  TByte buf[100];

  int i;



  memcpy(buf, EnterPgmMode, sizeof(EnterPgmMode));

  Send(buf, sizeof(EnterPgmMode), sizeof(EnterPgmMode_Reply));

  if (memcmp(buf, EnterPgmMode_Reply, sizeof(EnterPgmMode_Reply)) != 0) {

    for (i=0;i<(int)sizeof(EnterPgmMode_Reply);i++) {

      printf("%x: %x = %in", i, buf[i], EnterPgmMode_Reply[i]);

    }

    throw Error_Device ("Failed to enter programming mode."); }

}

-------------------------------------------



It seams as the answer is incorrect but I dont know what to expect.
