Toshiba T1 ROM Write

Hi, I have some T1 in different machines, the programs have timers, which are in constant changing, I'm trying to develop a small software that use the computer link protocol to change this timers, so nobody have to enter the TPDS to change them and by mistake (or not) change something on the program. I've already habe something working and can change a timer, the problem is that i can't find a way to write the changes on the EEPROM using the computer link protocol, so that in a power failure I don't lose the last changes made.

First of all, is there a way to do this? If yes, how can I? I've read the manuals u couple of times and just can't figure out how to do it.

Thanks, David
