All I get is ?C
 

When using my PC-DC cable and Serial Slave Disk I can get the > prompt and do the ? and get back the V103 message but when I send the dreamrip.srec file the first thing that happens is ?C unknown command. The same thing happens when I press the S key for some reason the DC is not accepting the S entries any ideas? I tried searching for this but I have not seen a simular post.
