    Apparently, the ESP32 UART has some kind of hardware flaw leading to
    an ESP32 reset actually not doing a full UART reset.<br>

    There is apparently no method to perform a full UART HW reset, at
    least I haven't found one. It seems this is an issue we cannot fix
    (in software).<br>
    <br>
    But I now don't think this is a new issue, and this also affects
    modules quite differently, no idea depending on what circumstances:
    on the current run, my car module has lots of FIFO overflows &
    quite some MUX framing errors, but not a single UART frame error.<br>
    <br>
    IOW, I don't think we should let that block the release.<br>

      This also produces a lot of unnecessary stress on the ESP's RX
      buffer, doesn't it?<br>
      <br>
      Channel 1 is the dedicated NMEA channel, 3 is POLL and 4 is CMD. I
      don't see why channels 3 & 4 are used for these by the modem,

        <br>
        (am I the only one experiencing this?)<br>
        <br>
        I've had multiple times of temporarily frozen modem
        communication over the last days on my car module. That's new,
        so I think we should try to fix that before releasing.<br>
        <br>
        On my bench module there's a clear correlation between the
        extended status query and the frame errors. It's also not
        related to the NMEA messages, I've checked that, they come at
        another second.<br>
        <br>
        Log excerpts below.<br>
        <br>
        With frame errors responses also occasionally get corrupted,
        e.g.<br>
        <font face="monospace">D (204251) cellular: mux-rx-line #3:
          Hologram",7</font><br>
        <br>
        I think the extended status responses now very often cause an
        overflow on the RX buffer when coming in together. Solution
        could be to split the queries and distribute over 2-3 seconds.<br>
        <br>
        I don't know if that will also fix the strange cold/warm boot
        difference with this, but maybe that's simply because the modem
        is faster with getting back to the network after a reboot, so
        the status responses become large quickly.<br>
