If the Host Computer Fails COMTEST
If the host computer failed COMTEST, there is a basic problem in transferring data through
the COM port. A computer technician should examine the computer.
If the Host Computer Passes COMTEST, but there are Still Problems
Some COM port problems are beyond the scope of this COM test program. These types of
problems tend to involve several devices within the computer that are trying to use the same
resources within the computer, each device affecting the others. A computer technician should
examine the computer to resolve these kinds of problems.
