Serial Port Transmitter will transmit all codes but the power on code for my tv doesnt work.

Running Lirc 0.9.0 Ive compiled on Fedora 14 x86. 
I have completely removed all lirc from the system before compiling this.

I recorded a conf file and it works great! 

The problem is the power will turn the tv off, but will not turn it back on.  Ive reinstalled and recompiled.

I also rebuild the transmitter ensuring I had the correct diode and resister.  Strange that only power on doesnt work

Any suggestions?
