And how can I in VB is set to 19200-8 - E - 2 this format, always can only be set to the 19200-8 - E - 1 this format, and the next bit machine communication only if a write parameters to the next bit machine error, the machine alarm, and read the hypogyny machine parameters is normal, even the whole communication process simulation of the original product or as long as a writing, speaking, reading and writing data parameters to the next bit machine error alarm, telecommunication lines, that is, sending and receiving and to three lines, there should be no other strange way to detect the original is not original, how may not be able to write to the next bit machine parameters? Are down only the format of the serial port Settings is a little different, could you tell me his - E - 19200-8, no. 2 in this format in the VB how to set out?

Using the latest version of MSCOMM control?CodePudding user response:
This latest version is also called "MSCOMM"? I use or 6.0, then can you tell me the item - 2 below is what mean? If search is less than the specific meaning,CodePudding user response:
I didn't come into contact with a serial port communication, only know a little fur,I think "- E - 19200-8, no. 2", it should be:
19200: data transmission baud rate
8: data digits
E: parity
2: stop bit two
As for VB6 serial port control can "stop bit" parameter is set to 2, I don't know,
You are used, these should clear than me, or else as "related parameters set mode" to try to know,

Settings properties
Set and returns the baud rate, parity, data bits, stop bit parameters,
Syntax
Object. Settings [=value]
Settings attribute syntax consists of the following parts:
Part of the description
Object expression, and its value is "applied" in the list of objects,
Value string expression, the communication port Settings, as described below,
Description
When the port open, if the value is illegal, the MSComm control an error 380 (illegal) attribute values,
The Value is composed of four Settings, has the following format:
"BBBB, P, D, S"
BBBB for baud rate, P surprising parity, D digits for the data, S to stop bits, the value of the default value is:
"9600, N, 8, 1"
In the table below lists the legitimate baud rate:
Set the value
110
300
600
1200

9600 (the default)
14400
19200
28800

256000
The following table shows that legal parity value,

E Even (Even)
M Mark (Mark)
N the Default (the Default)

O Odd (Odd)
S Space (Space)
