Hi there!

   These days I got my copy of WINCOMM and was very disappointed, when trying
   it. Though I know, that it's not a Wincomm Problem, I never realized it,
   while I was using Telix in a DOS Box.

   The Problem is, that Wincom only receives characters from my modem, when
   I rapidly move the mouse. From what I understand, is, that the comm driver
   of windows doesn't enable the IRQ line of the uart. So, if I move the mouse
   the driver also recognizes the characters of the other com ports. This is
   not true if I use the com ports 1 and 2, but the problem is connected to
   com port 3.

   Don't tell me about the entries I have to make in the system.ini. I entered
   the right keywords. My port adress is 3e8h on IRQ 5.

   Hope, someone can help (maybe someone wrote a new comm driver).

   Ah, I have another question. Are there any drivers for multi port cards
   using one interrupt for several serial ports for windows?
