Serial Communication Using VB

[khansaab21]

I m using VB6 to develop a software for serial communication with the controller.

I am quiet clear about how things go about in VB (as I have already taken a course of VB) but what i want to ask is how can i send A SINGLE BYTE IN HEX through the port??

Basically there are 4 instructions in hex which have their function defined in the controller software. And all 4 instructions are a single hex byte each.

1. 0xA3
2. 0xA5
3. 0xA6
4. 0xA7

These must not be sent as ASCII but hex only. How can i do that??
Plz help.

Try to convert your bytes from 8-bit integer to 1-character string. In VB6 it would be Chr(iYourInteger) . The string will not be human-readable neither as decimal nor as hex.

Hi...

send as mscomm1.output= &HA3

where 0xA3 will be sent as hex.... you can decode it inyour controller....
