I can successfully connect to MySQL from a DOS prompt, but when I try to connect from cygwin, it just hangs.
$/cygdrive/c/Program\\ Files/MySQL/MySQL\\ Serve
I have created a semi-fix for this that satisfies me. I ran cygwin.bat in cmd.exe, then typing mysql in- everything worked fine.
I realized right there that the problem was mintty.
Easy solution? Download Console2, and under settings you can point it to the cygwin shell. Restart Console2, run mysql and the output appears.
This is advantageous anyways, because Console2 has a more robust interface/customization than Mintty. I really like the transparency and color mapping options.
