Well, your inittab makes one thing clear... Your system creates one and
only one terminal, hardwired to the serial port and nothing else.
I don't know of any straightforward way to attach your keyboard to it instead, though, for a couple reasons:
- A keyboard is not a terminal. You cannot write data to a keyboard. You need to somehow multiplex two things into one device here.
- You could easily brick your machine here by messing up the primary terminal. Does it by any chance have a second serial port?
I've been looking for a way to multiplex two things into one device. Nothing yet. It might be necessary to create a pseudo-terminal device yourself and emulate it.

PTY(4) BSD Kernel Interfaces Manual PTY(4)
NAME
pty -- BSD-style compatibility pseudo-terminal driver
SYNOPSIS
device pty
DESCRIPTION
The pty driver provides support for the traditional BSD naming scheme that was used for accessing pseudo-terminals. When the device
/dev/ptyXX is being opened, a new terminal shall be created with the pts(4) driver. A device node for this terminal shall be created, which
has the name /dev/ttyXX.
New code should not try to allocate pseudo-terminals using this interface. It is only provided for compatibility with older C libraries that
tried to open such devices when posix_openpt(2) was being called.
FILES
The BSD-style compatibility pseudo-terminal driver uses the following device names:
/dev/pty[l-sL-S][0-9a-v] Pseudo-terminal master devices.
/dev/tty[l-sL-S][0-9a-v] Pseudo-terminal slave devices.
DIAGNOSTICS
None.
SEE ALSO
posix_openpt(2), pts(4), tty(4)
HISTORY
A pseudo-terminal driver appeared in 4.2BSD.
BUGS
Unlike previous implementations, the master slave device nodes are destroyed when the PTY becomes unused. A call to stat(2) on a nonexistent
master device will already cause a new master device node to be created. The master device can only be destroyed by opening and closing it.
The pty driver cannot be unloaded, because it cannot determine if it is being used.
