I want to open a serial port cash drawer connected to the client pc. I will have a record button on an asp page and when I click on it the drawer will open
A:
You'll need some way to communicate with the serial port. Web browsers typically cannot do this, so you probably want to call a program on the system.
One way to do this would be with Java Server Pages - you can call a Java application using JNI to communicate with the serial port. Look online for serial communication libraries using your favorite language.

Shame there's no "ser:" URI scheme. :-)
