How do I know an AT Commands Executed

[rplcmint]

Hello,

I'm having a problem issueing a simple AT command to a modem.

I'm using a MsComm control to open the modem port, so it will look like this:

With MsComm1
.portopen = true

.output "ATZ" 'Which should reset the modem quickly.

.portopen = false 'Drop the connection
end with

When I go check for the connection on Hyperlink..the modem did not receive my command.

Am I suppose to wait for an event to tell me that my command was successful? How do I do that.


I was also thinking that I am issueing the command wrong (probably should write it like this

MsComm1.output "ATZ" & vbCrLf


I need help cause this project is important.

I appreciate your input.
