[Linrad] Re: LINRAD-WSE

[Ivliev Alex <yandex.ru; ru1aa@xxxxxxxxxxxxxxxx>]

Hello Leif,
thank you for the help. My problem was really trivial,I needed only know the place on main Linrad window, where is
the frequency control field and "To set the frequency, right click and type in a frequency". I cannot find this stroke and pictures on your pages.
ON7EH sent me the pictures with this fields. 
Yes, I mean that Z=Hardware interface test 
I know long time what is serial and parallel port :}.
I have computers without  LPT also ,at first ,I'm going to buy  PCI parallel port, but now I bought computer for Linrad with
parallel port on motherboard, sorry, with Windows XP.
Thank you Roger W3SZ for the help with software( Direct I/O allowing hardware control).
Thank you Alberto  I2PHD.
Thank you all for the time spent my problem.
Alex
