| How do I maintain QConnect DOS on a hard drive? |

Sometimes, fixes need to be downloaded to a QCONNECT DOS terminal. If the customer is using a Hard Drive to boot QCONNECT, the emulator will look for an update file on the controller at each startup of QCONNECT. If it finds the file, ADX_UDT1:QMAINT.DAT, on the store controller, the following sequence takes place:
To show how this process works, let's assume that a fix for the QCONNECT emulator is required. The updated emulator, 7452emu.exe, will be zipped up to a file of any name and converted to an executable of any name. The utilities to use to do this are PKZIP.EXE and ZIP2EXE.EXE, respectively. The resulting xxxxx.exe file is then renamed to QMAINT.DAT and downloaded to the ADX_UDT1: directory. Once there, it will be detected by the QCONNECT emulator and downloaded, if it has not already done so. After it is downloaded, the terminal reboots. |
