            Bug ID: 52521
           Summary: RMS Express: Intermittent TCP connections between
                    program components
           Product: Wine
           Version: 7.1
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs at winehq.org
          Reporter: eric.wheez at gmail.com
      Distribution: ---

Context: RMS Express is a "Email over Radio" email-like client that interfaces
with sound modems (sound is then sent over radio to listening stations), much
like the old dial-up modems of the 1990's.  Its modems are separate programs
that connect to it over local TCP.

Problem: I would technically call this a minor bug, but since many users of
this program don't like using computers and might not try closing and
re-running RMS Express, I would consider it basically a 'crash' for this
program.  RMS Express's code can be peeked at with ILspy and ARDOP (one of the
modem programs) is open-source (available by joining
https://ardop.groups.io/g/main - and then later joining
ardop.groups.io/g/developers )

System:
 - Happens on Debain 10/x86 (VMWare) & on RPi4/armv7l (see
https://github.com/WheezyE/Winelink/)
 - Using wine-devel-7.1 (has been present since at least wine-devel-5.19 -
haven't tried earlier than that)
 - Happens whether using wine-mono or .NET 4.6 (so we can rule out a wine-mono
bug)

Installation: If you're interested, here are some quick install commands &
notes.

```
# Set up wine
# NOTE: wine-mono is also required for RMS Express!
winetricks -q win7 sound=alsa # for RMS Express
winetricks -q vb6run pdh_nt4 win7 sound=alsa # for VARA

# Install RMS Express & VARA HF/FM (no matter what their version numbers are)
# NOTE: ARDOP, VARA HF, & VARA FM need the user to configure soundcards after
installation.
mkdir rmsdownloads 2>/dev/null; cd rmsdownloads
    sudo apt-get install curl megatools p7zip-full -y
    # Download / extract RMS Express
        echo -e "\nDownloading and installing RMS Express . . .\n"
        wget -q -r -l1 -np -nd -A "Winlink_Express_install_*.zip"
https://downloads.winlink.org/User%20Programs
        7z x Winlink_Express_install_*.zip -o"WinlinkExpressInstaller"
        wine WinlinkExpressInstaller/Winlink_Express_install.exe /SILENT

    # Download / extract VARA HF
        echo -e "\nDownloading VARA HF . . .\n"
        VARAHFLINK=$(curl -s https://rosmodem.wordpress.com/ | grep -oP
'(?=https://mega.nz).*?(?=" target="_blank" rel="noopener noreferrer">VARA HF
v)') # Find the mega.nz link from the rosmodem website no matter its version,
then store it as a variable
        megadl ${VARAHFLINK}
        7z x VARA\ HF*.zip -o"VARAHFInstaller"
        wine VARAHFInstaller/VARA\ setup*.exe /SILENT

    # Download / extract VARA FM
        echo -e "\nDownloading VARA FM . . .\n"
        VARAFMLINK=$(curl -s https://rosmodem.wordpress.com/ | grep -oP
'(?=https://mega.nz).*?(?=" target="_blank" rel="noopener noreferrer">VARA FM
v)') # Find the mega.nz link from the rosmodem website no matter its version,
then store it as a variable
        megadl ${VARAFMLINK}
        7z x VARA\ FM*.zip -o"VARAFMInstaller"
        wine VARAFMInstaller/VARA\ FM\ setup*.exe /SILENT
cd ..
rm -rf rmsdownloads
# NOTE: RMS Express requires a free user account, which you can sign up for on
first run of the program.
```

Terminal output: The terminal output segments when ARDOP connects to RMS
Express (vs when ARDOP fails to connect to RMS Express) look basically
identical
(process numbers -and also the address in ImmReleaseContext- change every run)

I'm excited to say I got this program working on Android (without root)
recently thanks to box86/Termux/PRoot https://youtu.be/FkeP_IW3GGQ?t=23 .  Lots
of ham radio operators are using really old Windows PC's to run this software
on their message servers. Many people want to take this software with them in a
backpack too (without getting an expensive Windows tablet) or strapped to their
radio on a Raspberry Pi, and I think solving this weird intermittent TCP
connection issue in Wine could help make using wine with RMS Express pretty
popular.
