I want to use the 669iaplib, but not as HUGE ROM model.
Is there anything else to change, or just ERET to RET?

My problem is that i only have a 4 wire RS232 connection.
Rxd, Txd, GND and RTS.

I try'ed to use DTR and RTS to control RST and PSEN
In my case RTS to control PSEN.
FlashMagic send a 'U' to set up the Baudrate.
My software detect that 'U' echo back 'U.* and then let the "HARDWARE WATCHDOG TIMER (ONE-TIME ENABLED WITH RESET-OUT FOR P89C660/662/664)" make a  reset for me.
This works not so good, about 1 of 5.

At what point will FlashMagic send 'U'. Before RTS or under RTS or after RTS?

So i tried "STARTBOOTROM" insteed, and it works.
But FlashMagic activates RTS when it programming my device, so when it try to restart my software "PSEN" is low and the device will go into "ISP mode" again.

Is this a BUG or is there a way to keep RTS inactive when running STARTBOOTROM?

I want to have both option aviable
