I would use a serial modem, assuming your server has a serial port...
and then configure a tty on that serial port, along with the modem
CentOS has mgetty, so in /etc/inittab, you add a line like...
S3:345:respawn:/sbin/mgetty -x3 ttyS0 (for com1 which is dev/tty0)
and configure your modem options in /etc/mgetty+sendfax/mgetty.config
now, you can use a dialup terminal program such as minicom, hyperterm,
etc and dial into that modem on the CentOS system, and get a serial
sadly, I haven't set this sort of thing up in so many years, Ive
forgotten all the specifics. these days, we just use ssh over the internet
