I just went through this same exercise last week. Here is a link to
the source code of IMSAI's original paper tape loader which does
exactly what you're looking for. You will probably have to modify it
to suit your particular serial interface and memory map.
paper tape loader.asm
As an aside, here is a video of my IMSAI using this loader to bring up
a copy of Altair 4K Basic.

I actually used a version of Dave Dunfield's monitor which includes a hex
upload module. A few of the monitors I have from different sources have hex
upload capabilities.
That's obviously a bit more involved than the paper tape loader but is a
bridge to other things.
