I'm attempting to connect two Oracle VirtualBox guests (Both CentOS 8 running on Windows 10) and have one guest connect to the serial port (/dev/ttyS0) of the other guest and have to go through the login process.... Unfortunately I've been unable to do this
I've configured the serial ports for both guests to use "COM1"... Set their Port Mode to "Host Pipe"... named the pipe on both machines "\\.\pipe\serial1"... I selected "Connect to existing pipe/socket" on the slave guest
I've tried to use putty/cu/minicom to connect from the slave to the master... Unfortunately a login prompt never appears... If it matters both VM guests have their network adapters set to "bridge adapter" and can connect to the internet and LAN fine
If someone can offer me any guidance on this I would appreciate it!
I have a modem connect it to ttyS0 , in unix sco i know i can disable and enable the port , how can i do this , is there a command that will allow me to do this.

systemd-getty-generator
SYSTEMD-GETTY-GENERATOR(8) systemd-getty-generator SYSTEMD-GETTY-GENERATOR(8)NAME
systemd-getty-generator - Generator for enabling getty instances on the console
SYNOPSIS
/lib/systemd/system-generators/systemd-getty-generator
DESCRIPTION
systemd-getty-generator is a generator that automatically instantiates serial-getty@.service on the kernel console(s), if they can function
as ttys and are not provided by the virtual console subsystem. It will also instantiate serial-getty@.service instances for virtualizer
consoles, if execution in a virtualized environment is detected. If execution in a container environment is detected, it will instead
enable console-getty.service for /dev/console, and container-getty@.service instances for additional container pseudo TTYs as requested by
the container manager (see Container Interface[1]). This should ensure that the user is shown a login prompt at the right place, regardless
of which environment the system is started in. For example, it is sufficient to redirect the kernel console with a kernel command line
argument such as console= to get both kernel messages and a getty prompt on a serial TTY. See kernel-parameters.txt[2] for more information
on the console= kernel parameter.
systemd-getty-generator implements systemd.generator(7).
Further information about configuration of gettys can be found in systemd for Administrators, Part XVI: Gettys on Serial Consoles (and
Elsewhere)[3].
