[Solved] P550 Unable to access Console

I have recently aquired the following machine:
IBM,9113-550

Up until yesterday we could connect a dumb terminal to serial port 1 and get console login. However the dumb terminal died. We are now using a laptop with a null modem cable attached to serial port 1. This works perfectly for all of our other pseries servers except this one. As far as I can tell everything is setup the same as the other servers.

Code:
lsdev -Cc adapter | grep -i serial
vsa0 Available LPAR Virtual Serial Adapter
vsa1 Available LPAR Virtual Serial Adapter
 
lscons
/dev/vty0
 
cat /etc/inittab | grep tty
cons:0123456789:respawn:/usr/sbin/getty /dev/console
tty1:2:(ff:/usr/sbin/getty /dev/tty1
vty1:2:(ff:/usr/sbin/getty /dev/vty1
 
termdef
vt100
 
lsattr -l vty0 -a speed -R
19200

getty is running:
Code:
ps -ef | grep getty
root 274584 1 0 17:31:34 vty0 0:00 /usr/sbin/getty /dev/console

Console Assignment:

Code:
PATHNAME of console [/dev/vty0]
Enable for LOGIN yes
PATHNAME of console LOG FILE [/var/adm/ras/conslog]
SIZE of console LOG FILE [32768]
Console log VERBOSITY [1]
Console tag VERBOSITY [0]

TTY Config:

Code:
TTY vty0
TTY type tty
TTY interface vcon
Description Asynchronous Terminal
Status Available
Location
Parent adapter vsa0
PORT number [0]
Enable LOGIN disable
TIME before advancing to next port setting[0]
TERMINAL type [vt220]
FLOW CONTROL to be used [xon]
STTY attributes for RUN time
hupcl,cread,brkint,icrnl,opost,tab3,onlcr,isig,icannon,echo,echoe,echok,
echoctl,echoke,imaxbel,iexten
 
STTY attributes for LOGIN [hupcl,cread,echoe,cs8]
LOGGER name []
STATUS of device at BOOT time [available]
STREAMS modules to be pushed at OPEN time [ldterm]
INPUT map file [none]
OUTPUT map file [none]
CODESET map file [sbcs]
POSIX special control characters:
INTERRUPT character [^c]
QUIT character [^\]
ERASE character [^h]
KILL character [^u]
END OF FILE character [^d]
END OF LINE character [^@]
2nd END OF LINE character [^?]
DELAY SUSPEND PROCESS character [^y]
SUSPEND PROCESS character [^z]
LITERAL NEXT character [^v]
START character [^q]
STOP character [^s]
WORD ERASE character [^w]
REPRINT LINE character [^r]
DISCARD character [^o]
Apply change to DATABASE only no

Have tried rebooting several times with the laptop connected no output is sent to the laptop. I am using hyperterminal with the following settings:

Code:
COM1
19200
8
N
1
Xon/Xoff
vt100

Any help would be greatly appreciated.

I did manage to get the console to respond by hitting Ctrl Q.
