Why does it do only one curve?
I have installed msys and gmpecm as described in the readme file and tried to do some curves on the C205  entered this line:
ecm c 372 1e6 <1701c205 >1701c2051M.out I intended to get 372 curves, but I got only one. What did I do wrong?

I just tried to retrace your problems. The only scenario I got such a behavior was when a factor has been found and the cofactor is probable prime.
Could you post your output file, please?

Here it is  I renamed it to .txt for uploading.
I see no factor in this file  it only gives the time steps one and two took.

Unfortunately, I wasn't able to reproduce your problem. I tried the same number with the same command line, but it worked for me.
I could think of two more problem sources: 1. Maybe there is something wrong with input/output. Just enter the number at command line ("echo <number>  ecm <...>") and don't redirect the output to a file. 2. Maybe your ecm file is somehow corrupt. Try recompiling it or take a suitable binary from this thread. Hope this helps!

If the input file doesn't have a terminating newline character after the number, gmpecm will quit after the first curve. Just add a newline to your input file and you should be ok.
