You can use the AccessPort implement the features you want but you want to develop a software estimates are difficult because this is the driver stage to the development of VB estimates do not

CodePudding user response:

No other software in use at the same time that if the COM to be done to you can search the VB source should be a lot of serial port development

CodePudding user response:

reference simon__sun reply: 3/f

if the COM no other software is in use at the same time to that can be done to you can search the VB serial port development source should be a lot of

COM have another software in use, I is sending data to monitor it

CodePudding user response:

That can't do

refer to the second floor simon__sun response:

I also want to do a PC and PLC communication program, no clue

CodePudding user response:

AccessPort during monitoring data does not use the monitor serial port,

CodePudding user response:

All kinds of serial port monitoring software, an online search a lot of, will not affect the existing communication,

More stupid way is the communication of serial port 2 foot to the other serial port 2, the 3 foot also received another 2 serial ports, so monitoring to send and receive,

CodePudding user response:

Code a lot of online, yourself tidy,

CodePudding user response:

Use portmon software,
