Hi
I finished a project using a boot loader program under windows for code development.
I need to be able to upgrade my firmwere remotely over a modem since a modem is built in my project already.
I searched the forum and found this :

J. Guy said
you will have to write software, since you are talking through a modem. But the software to change code bytes is built into the chip. All you have to do is call it.

I have 2 problems, 1st I have to reset my processor for the bootloader to work, upon reset the microcontroller waits for 300msec for the windows bootloader program to start sending bytes, if timeout ocured then normal program execution otherwise flash gets updated.
How do i reset my microcontroller over a modem?
It would be nice if i can use the same free windows bootloader program to program my chip over the modem. Is this possible or do i have to write my own windows bootloader program and re invent the wheel as J. Guy kindly stated.
Any suggestions ?
thanx
