MScomm object and Hex values

[capone67]

Hi Gang

How do I send a Hex number to the serial port on my system using the mscomm object? Also how do I string together a bunch of hex numbers to be sent to the comm port as one command? for example &H2 + &H3 + &H4 all get added together but I need to send them as 3 seperate numbers. Would sending them to the mscomm.output one at a time be the equivalent of sending them all at once not added together?

Have a look at the code I posted in thread222-38441 Conversion of 4 bytes to a single. The code can easily be downsized to 3 bytes (and Hex values) _________________________________

Send it in a Byte array, you should be in binary mode.

MSComm.InputMode = comInputModeBinary

Dim ByteArray(2) as Byte

ByteArray(0) = &H2
ByteArray(1) = &H3
ByteArray(2) = &H4

Mscomm.Output = ByteArray()
