Need to Manually set baud rate for USB-Serial

[sjf-control]

I am trying to write a ruby script that automatically processes/controls a device thru a USB/Serial adapter. (Keyspan in this case, but I have others as well.) My problem is that I need to change the baud rate from the default 9600 to 115200.

In other systems (FreeBSD) I would execute "stty -f /dev/cu.KeySerial1 115200". But this doesn't seem to actually change the baud rate in Leopard. I know the hardware is working, since "screen /dev/cu.KeySerial1 115200" works fine.

I've search the web, but have come up empty. Any help would be appreciated.

Thanks,
sjf

Well, in case anybody else is also looking for the answer...

In ruby, the solution appears to be the "Ruby-Serialport" gem -- http://ruby-serialport.rubyforge.org/

In Python, try "pySerial" http://pyserial.wiki.sourceforge.net/pySerial
