Hi VB Type people,,...

I am thinking of taking on the task of writing a tank guaging program in VB6.

What I need is some resources for RS-232 devices.

The oil/fuel tanks that I will be writing the program for receive send their information through a PLC (programmable logic control??)

Anyone know of any resources for RS-232 device interfacing with VB programs?

I hope I am stating all the correctly.

thanks,
kevin rea
