VB6 - How do I call routines in one exe from another exe like they are in same exe

I have a VB6 exe that has a serial comms driver involved.
The issue is that sometimes whilst awaiting a response form the serial port, some other event occurs that consumes CPU for a time and as the code connot respond to serial data the device times out and errors.
I need to either be able to give priority to the serial comms code or split this serial control ot to a separate exe or somehting so that it cannot be interrupted but I then need some way to call its routines and recieve data from it.
Any help would be appreciated.

In .net it's called multithreading.  Not really supported out of the box in VB6.
