This is not necessarily a very big problem. A Com Overrun happens when your
computer has to ask your modem "what did you say?" There are a few
reasons why you will get these.
COMnFIFO=1
COMnRXSize=8
COMnTXSize=0
MinTimeslice=20
WinTimeslice=100,50
COMnBuffer=256
The "n" in the 1st, 2nd, 3rd, and 6th lines is the number of the COM port your modem is on (so if you're on COM2 it should read COM2FIFO=1). If the lines are there, modify them. If they are not there, add them.
