The Brewer software installation on Linux and DosBox-X
Tested on Linux LMDE6, Mint 21.3 and Ubuntu 22.04 LTS

dosbox-mb6 folder is not used in this installation!!! 


1. Install DosBox-X from https://dosbox-x.com

  Manual install:
   $ flatpak install flathub com.dosbox_x.DOSBox-X


2. Run the DosBox-X and test successful instalation:

    $ flatpak run com.dosbox_x.DOSBox-X
   

3. Set serial port (/etc/group) -> (sudo chmod 666 /dev/ttyUSB0)
    $ ls -l /dev/ttyUSB0
    command to set for "brewer" user permanently
    $ sudo adduser brewer dialout
    or
    $ sudo usermod -aG dialout brewer

6. Installation of the Brewer software.
   a) create a folder in your Home directory to copy the Brewer software, for example "B199" 
            
    $ mkdir ~/B199
      
   b) copy Brewer software there (/home/brewer/B199) -> brew410
      and brewer-x.conf, brewer-x.sh, create bdata folder

   c) edit brewer-x.conf

      Brewer serial com port 1 , fixed port
   
     [serial]
      serial1=directserial realport:ttyS0
    
     or Brewer serial com port 1 , USB-RS232 converter port
      serial1=directserial realport:ttyUSB0

     [DosBox]  (optional)
     title                                           = Brewer #199
     working directory default          = /home/brewer/B199

     [autoexec]
     mount C /home/brewer/B199
     C:
     cd \brew410
     Setdate
     set brewdir=c:\brew410
     gwbasic main.asc /f:10
     
   d) edit Brewer starting script - brewer-x.sh
     flatpak run com.dosbox_x.DOSBox-X -date-host-forced -conf ~/B199/brewer-x.conf

   e) Start the Brewer 
     $ ./brewer-x.sh
     or
     $ flatpak run com.dosbox_x.DOSBox-X -date-host-forced -conf ~/B199/brewer-x.conf

Remarks

Command Setdate in [autoexec] section of brewer.conf above can be replaced by SetOPST. This command (program SetOPST.exe) set correct date to OP_ST file (like Setdate) and also schedule name.
This command is usefull when PC command is used at the end of ED.RTN to restart DosBox and when schedules must be changed automatically.
Using of SetOPST:
SetOPST parameter			parameter is a schedule name

a) SetOPST sche.skd	...	write "sche" schedule to OP_ST.nnn to start automatically with main program 
b) SetOPST sche??.skd	...	write sche01 .. sche12 schedule based on actual month
c) SetOPST sche???.skd	...	write sche001 .. sche366 schedule based on actual day of year

Set up SUB-Serial converters for the same COM port after computer reset

1. Plug the device (I have converter from papouch.com) 
2. run the following command, on the proper device; 
$ udevadm info --name=/dev/ttyUSB0 --attribute-walk | grep '{serial}\|{idProduct}\|{idVendor}'
 
udevadm starts with the device specified by the devpath and then walks up the chain of parent devices. It prints for every device found, all possible attributes in the udev rules key format. A rule to match, can be composed by the attributes of the device and the attributes from one single parent device.
 
3. Create a file in /etc/udev/rules.d, typically named 99-usb-serial.rules. Each converter I use has unique attribute "serial". (Producer name is Papouch.)
 
SUBSYSTEM=="tty", ATTRS{serial}=="PPUQFPPX", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", SYMLINK+="papouch"
 
4. Force re-running the scripts (or reboot)
$ udevadm control --reload-rules
 
5. Test if symbolic link exists
$ ls -l /dev/papouch
 
Then you can add more lines for another adapters in /etc/udev/rules.d/99-usb-serial.rules with SYMLINK+="your_addapter_name_1,2.."

Set up Time synchronization
install NTP

$timedatectl status
$timedatectl set-timezone UTC
$timedatectl set-ntp true

edit /etc/ntp.conf

for example:
# You do need to talk to an NTP server or two (or three).
server timer.chmi.cz

$service ntp restart
$ntpq -pn

Set up Samba server to share data with Windows network 

install Samba server ->
https://www.howtoforge.com/tutorial/debian-samba-server/

Add Samba users {as root}
Samba uses it's own password system so users need to be added by root. Note that the users have to exist in /etc/passwd 
# smbpasswd -a brewer

edit /etc/samba/smb.conf

#example of set up of shared folder, at the end of smb.conf
[B199]
path = /home/brewer/B199
browseable = yes
read only = no
create mask = 0775
directory mask = 0775
