Apologies in advance if this has been asked and answered, if it has I was unable to find a resolution.

Have a TP-Link WR1043ND with Chaos Calmer loaded, seems to be working good.  In playing with it I was trying to get a prolific USB serial port to setup as a serial console.  Just in case I lost access but the device was not bricked.   the PL2303 driver loads fine and the device is set to ttyUSB0.   With that being said, when I connect to the serial port with SecureCRT on a windows system all I see at 115200 is garbage characters.   Actually, a constant string of "p" scrolling across the terminal session.   Have the setting set to 115200, 8, n, 1 with no flow control.  I'm using a null modem cable.   

Thanks in advance.

Ok, I was able to get it working without a login.   Turns out one of the Prolific serial interfaces I have doesn't cooperate very well.   The newer one works just fine.     Here is what I did;

opkg update
opkg install kmod-usb-serial kmod-usb-seral-ftdi kmod-usb-serial-pl2303

kmod-usb-core, kmod usb-ohci, kmod usb2 were already installed.   

opkg install agetty

modified /etc/inittab with the following:
#::askconsole:/bin/ash --login
USB0:2345:respawn:/usr/sbin/agetty -L ttyUSB0 115200 -n -l /bin/ash
USB1:2345:respawn:/usr/sbin/agetty -L ttyUSB1 115200 -n -l /bin/ash


reboot. and was able to get the console without a login.

The discussion might have continued from here.
