Using XP to dispell ambiguities of Linux : I have completed a VT100 board (works well with MicroMite in stand-alone mode) I would now like to try it as USB-Serial adaptor. I (for comparison) have a SparkFun adaptor. TeraTerm finds both the VT100(Silicon Chip USB Serial Port (COM3)) and the SparkFun unit(USB Serial Port (COM7)) MMEdit finds the SparkFun unit (Maximite Connected Com7) but not the VT100 (Maximite Disconnected) FWIW I have the same thing in Linux using MiniCom. I.E. MiniCom finds the SparkFun but not the VT100. BUT The SparkFun will show the MicroMite splash screen but not communicate further ....... First things first though ... TeraTerm vs MMEdit (and BTW HyperTerm) with XP .... |

Hitsware, I am confused when you say that MMedit does not find the unit. It is not the job of MMedit or TeraTerm to find the ports, that's the job of the OS/drivers. If the COM port is not there then that's not the fault of the program. ![]() |

Graeme, I evedently have the drivers installed, because TeraTerm recognizes both units. " that's not the fault of the program " I am NOT blaming the program. I just want to figure out what's going on. There seems to be an affinity between TeraTerm and the MicroMite and related products that is not shared with other terminal emulators. This problem is not shared with the MaxiMite or DuinoMite (FWIW) |

If I was looking for a VT100 terminal program, I would choose TeraTerm over MMEdit any day. The terminal in MMEdit is very limited and was never intended to replace TeraTerm. If you want to edit programs in MMEdit and test them conveniently, I believe the terminal in MMEdit does the job. I have no idea why MMEdit is unable to find your device. If Windows (and TeraTerm) see it, MMEdit should be able to as well (Provided the port is not in use). Go to File/ Configure Maximite. Select 'Find Ports' and see what is listed. Some devices such as the original Maximite will have a *MM* to indicate it is (probably) a Maximite and other USB-serial converters will be listed without the *MM* ![]() You may need to close all but the edit window before plugging the USB device in or Windows can get confused. Windows and USB tends to et confused easily. Jim VK7JH MMedit |

(Maximite Connected Com7) >>but not the VT100 ................... (Maximite Disconnected) There's some subtlety missing. Maybe with the VT100 I.D. ? |

Even if the VT100 terminal appears differently to Windows, MMEdit shouldn't care. MMEdit is supposed to find ANY serial port. It is only if it is determined to be a Maximite that the *MM* appears but that doesn't matter, the serial port should still appear in the list and work OK. As you know the port number, what happens if you just select that port without doing a search? I don't have a chip suitable to use the VT100 code so I am unable to guess what is not working. I can understand if the 'load and run' command wasn't working but a simple connect with chat doesn't care about versions of 'mite etc. Jim VK7JH MMedit |

> MMEdit is supposed to find ANY serial port Right. That's what I'm saying. MMEdit (and HyperTerm) do not recognize the VT100 as they do the SparkFun. |

What version of the VT100 firmware are you running? Jim VK7JH MMedit |

1.2 MMEdit2 |

I am not sure if the baud rate has any effect with the VT100 terminal but if it does: MMEdit2 does not have the option to change serial port baud rates in the GUI yet. Close MMEDit2 then Open MMEdit2.inf (in the data folder up from the program folder) and down the bottom of the file is a [Serial] section Check in the line SerialSpeed = 38400 that the baud rate is correct. Save any changes then restart MMEdit2 Have you used the original MMEdit program? According to the tests I have done, MMEDit2 is better than MMEdit when it comes to handling serial ports but I have not done much wor on it for a while. Jim VK7JH MMedit |

[Serial] comport = com7 SerialSpeed = 9600 CharDelay = 0 LineDelay = 30 Edit Delay = 150 Auto connect = 1 Command delay = 200 Serial poll timer = 100 edited to 38400....no change |

What happens if you change the comport to com3 That is the port number that TeraTerm found the VT100 on. I had a read through the VT100 description and could not see any reason for it it not work. I have no problems with the Silicon Chip driver hear (windows 7 and Windows 8.1) Please try with the original MMEdit. Jim VK7JH MMedit |

Jim, Thanks for the help ! Do (or have)you actually have a VT100 + MicroMite running from USB with MMEdit ? |

No, I don't have a chip to load the VT100 firmware onto but it uses the same driver as the maximite and I have had no problems with the maximite. Not to long ago I spend days trying to sort out a USB problem and was ready to toss the device out until I discovered the USB cable was at fauly. That cable has now seen the sharp end of the cutters and no more problems. I have ordered a chip but I am not sure how fast it will get here and then I need time to set it up. I was hoping someone else was able to test the setup but no takers so far. Jim VK7JH MMedit |
