Hello all,

Im trying to use the MSComm object to talk through a serial port, but I can't seem to get the thing working right. This is how I declare and use it:

Private PORT As MSComm

PORT.InBufferCount = 0
PORT.CommPort = 1
PORT.Settings = "9600,N,8,1"
PORT.PortOpen = True

This should work, but I keep getting error '91', which says the object variable or with block variable is not set. Can anyone tell me why this is...?

Do I need a statment saying "Set PORT = NEW Something" or something like that? Please let me know...


Thanks,
Damann

I've already added that and it makes me use the object, it's not bombing saying object not defined or anything like that. When it sees the first call using the object it cries:

PORT.InBufferCount = 0

When it sees this call it gives me the runtime error '91': object variable or with block variable not set. So I don't know what the hell I'm doing wrong.

You might try:

Set Port = MSCOMM

Assuming MSCOMM is the name of the com control on your form.

But really, you don't need to go through all that. Just access the MSCOMM control directly. ( unless you have a reason to have to assign the control to an object variable )

my control is called MSComm1. this is how i use it. you have to set its properties as well.

MSComm1.CommPort = 1
MSComm1.PortOpen = True
