VB and RS232

[sunmix]

Hi, is there any websites that can explain how to link Rs-232 and VB together? There's an instrument that feedback signals from 0- 200 and I need the VB to detect it so that I can do program what I want to control.

Hi,

you can use a subroutine "SendSerial (char as String) to communicate. But is it possible to read a value with the RS232?

I couldnt fount anything ....

Does anybody use the RS232 in such a way?

I have used it before - best place to look at the moment is down in the downloads section under macros of the forum. CJmerlin has used it to control a microcontroller, based on my experiments.

Any luck with the VB and RS232 I am looking to control a Boxford Duet which requires serial to control the motor and reports back with the RPM, does any one know how I can trigger a serial send with a G-Code and control depending on returned value, new to this so any help would be appreciated.
