Serial Port Redirector, HELP!
« on: Jan 14th, 2013, 7:54am »		 Quote Quote  Modify Modify
Hello!
I need help! There is a scheme.
Need to make sure that the modem answers the call, and immediately redirect to one physical COM port.
ftp://77.47.130.90/in/scheme.png
Serial Port Redirector as shown did not work.

Thank you.

Please answer the following questions:
 
1. Are both of the devices hardware? What about COM ports?
 
2. Will the devices communicate somehow with the PC? (not only with each other);
 
3. How will you configure the modem to accept the calls automatically?  
 
 
P.S. You used first TCP-port. Please note TCP ports from 1 to 10000 are reserved for the operating system. Try to use Serial Port Redirector with any TCP port >10000

PC should only have access to COM 1.
Modem is installed on COM 2, but it must be done so when a call comes (RING), he picks it up and forwards to COM 1 for data exchange.
 
About 3.
In Windows HyperTerminal to send a commands
ATS0 = 1 auto answer on the first ring
AT+IPR = 9600 to the serial port
AT&D0 to ignore the DTR (for a 3-wire cable to the modem)
AT&W0 Save settings
 
That is such an algorithm.
 
P.S.
Network serial port kit public access to COM 2, and then Serial Port Redirector redirects to COM 1. That's just the opposite to replace the modem.

I`m still not sure I understand you correctly. So what issue did you encounter? Did you change the TCP-port?
