I have a need to connect a serial device to EXCEL to capture some ascii
string sent by this device on the speadsheet, I want to build a small VBA
program but I have no information in how to logically connect excel to the
com port.
If anybody has a sample program with comments this will help me a lot.
Thank you and regards
