Com port number / IRQ number for DOS not staying the same after restart.
Posted on 2007-10-05
I have a customer that has a DOS aplication that prints directly to the com port ( and COM2 is hard coded into the application)
The computer's com port under device maniger shows the port as COM2, but under DOS it shows COM1 ( when using MODE command)
In order to get DOS to see the COM port as COM2, the user has to go into device maniger and change the settings, change it back, and the use the program in question.
Every time the computer starts up, it the com port under dos shows COM1, until it is changed manually by the user.
Can the com port be re-directed (or the IRQ changed from the command line ?)
