- Get list of all ports
- Send a command with known response to each port in turn
- Monitor response.

For example send AT command "AT?" to each port. If Returned data is "ATOK" then you know is connected an AT compatible device. If not then try next port.

Now you can check identity of connected device.

Good luck.

There is no such thing like that using serial ports. You must study how to use USB. You can find source by fr3nsis in the fourm, it will help you.

Good luck.

Hello,

I know it has being a long time since this post was created, but I am trying to communicate with an Encoder using Silicom Lab CP210X USB/UART bridge , at first I use a RS 232 class , couldn't get any reply from the encoder ( The hardware is good as the hotel is using it during the day with the C++ application who come with it) , then I tried AnySerialPOrt , a very nice C# app written by Orhan who let you build driver for serial port, still no reply, the format in which the string has to be sent is at follow.

The EIA RS232C standard interface is employed to connect ADEL interface network system with the hotel management system.
3.1.2 Data Format

Data format: 1 start bit, 1 end bit, 8 data bits, no verification; The communication rate is from 2400bps to 19200bps.
3.2 Data Protocol

3.2.1 Control Character

STX (0x02):Tag the beginning of the data.
ETX (0x03): Tag the end of the data.
ENQ (0x05): Test the connection.
ACK (0x06): Response to the end which transmits the data and show that the transmitted data is correct.
NAK (0x15): Response to the end which transmits the data and show that the transmitted data is wrong.
RS (0x1E): Tag the beginning of the new field (region) and is followed by the field identification code.
3.2.2 Information Format

Information format: <STX>ddssff[data]<ETX>cc
When the receiving end gets the information complying with the above format, it will respond with “ACK” if the calculated verification is same as the received verification. Otherwise, it will respond with “NAK”. The above responses (ACK and NAK) are applied to check the data integrality. They show neither the data content nor whether the execution result is right or wrong.

Information Field
Description
dd
Destination address, target (client) address
ss
Source address which tags the information source
ff
Command or answer code
[data]
Data region (optional)
Destination address:
2-byte; virtual value: 00 to 99. Receive the information destination address or designate the client end to execute the commands.
Source address:
2-byte; virtual value: 00 to 99 (00 is reserved by the system). Tag the information source.
Command code:
1 byte ASCII code. Specify the command to be executed.

Check character:
2-byte;
Algorithm: Use 0x00 as the seed to do XOR with all the data after STX. The result of each XOR will be used as the new seed for the next XOR. The final 1-byte result will be transformed into a 2-byte hexadecimal ASCII code.
Example:
STX
0x30
0x39
0x52
ETX
C1
C2

First calculation: 0x00 XOR 0x30 = 0x30
Second calculation: 0x30 XOR 0x39 = 0x09
Third calculation: 0x09 XOR 0x52 = 0x5B
Forth calculation: 0x5B XOR 0x03 = 0x58
Verification code of the first byte (C1): 0x5 ->ASCII 5 = 0x35
Verification code of the second byte (C2): 0x8 ->ASCII 8 = 0x38

/////////////////////////////////

I build the HEX convert module to XOR the data, when I send a string like <STX>0103E<ETX>CC, I expect a ACK or NAVK back if my dta is incorrect , but herre nothing, just:
=======================
<20110403184211.296 SYS>
Set timeouts: ReadInterval=100, ReadTotalTimeoutMultiplier=2000, ReadTotalTimeoutConstant=2000, WriteTotalTimeoutMultiplier=0, WriteTotalTimeoutConstant=0
<20110403184251.335 SYS>
Purge the serial port: RXCLEAR, TXCLEAR
<20110403184257.523 TX>
<STX>0103E<ETX>44
<20110403184439.616 SYS>
COM port is closed

======================

when checking with a serial monitor the data TX and TX to the enocder from the C encoder software I get those stange ASCSII char :

===================
000043: I/O Request (UP), 29.03.2011 16:47:51.090 +0.0
IOCTL_SERIAL_PURGE: Purge requests
000044: Write Request (DOWN), 29.03.2011 16:47:51.090 +0.0
Buffer size: 0x16 bytes
FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF 7E ˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙~
FF 00 DF 0B 17 7E ˙.ß..~
000049: Read Request (UP), 29.03.2011 16:47:51.121 +0.0
Buffer size: 0x1 bytes
Status: 0x00000000
7E
...ETC>>>>>>>>>>>>>
==================

I think this is coming from the silicom Lab bridge ...

I would appreciate any ideas or suggestion or if anyone has worked with Silicom lab bridge before ..
Cheer's

Alan

In fact dr dre beats studio headphones, the new school days in *******, shandong dongying city in a school in heilongjiang, Harbin minjiang elementary school... Many Chinese school Red dr dre headphones, has a garden and the elements. Even some school brand edge is hung with "Chinese garden" and signs.
Many of the details of the book became a classic case of education workers, some teachers will take classmates said to "ZhangDouDou" folding headphone, "WangDouDou", most of the bad character called "steel beans".
But SunYunXiao and bestseller, "the good mother is better than a good teacher," the author of YinJianLi all say "China is not true top studio headphones," the garden.
