This seems to be very few people really use a success, or out, no one is provided with PBapi to be usable

CodePudding user response:

Receive data should be written in the oncomm event of ole, receives the data will be automatically triggered, so you the output code behind no
If This.Object.com mevent=2 Then//a data
Ls_data=https://bbs.csdn.net/topics/ole_1.object.Input
Ls_tempstr=ls_data ls_tempstr +
Sle_1. Text=ls_tempstr
End the if

And don't have to close a serial port receives the data

Open the serial port code can be written in the window, such as the open event of

After you send the data to look in the debug oncomm event has no data out

Didn't come out no data to show you there hardware (could you send his wrong, so it is not send data out)

CodePudding user response:

Can send 0 x00, these characters you sure no problem, using mscomm control

CodePudding user response:

reference hchjjun reply: 3/f

0 x00 can hair, these characters must be no problem, you'll use mscomm control

Don't know what you're saying
