Hi,

How much is the Dontronics one?
I have a Keyspan 4-port USB-to-RS232 that doesn't include the DTR signal, so I'd be curious to know.

In any case, I found a way around the DTR signal, and it's pretty "inexpensive" code-wise.

I posted this the other day:

It allows you to use the MCSP bootloader without the DTR signal.

Cheers!
