Serial Port Access

1) How do you configure COM ports (baud, etc)?

2) How do you display received data to the screen?

Thanks!

Actually, they are in linux just devices, without any baudrates. Most of the applications, using the comports, are able to define the baudrate them selfs. So each program is able to talk to the comport with the baudrate needed by that specific program.

2) How do you display received data to the screen?

Do you mean data received by the comports, or data received by a networkcard ?

Thanks!

1) I need to manually set up a serial port in order to communicate with an external device. I need to configure as follows:

Baud: 115.2k
Data Length: 8
Stop Bits: 1
Parity: None
Handshaking: None

2) I would like to capture the Rx data from the serial port.

BTW, I'm currently using RedHat 7.2.

Thanks!

I am struggling with the correct place to configure X-on/x-off for serial connections from VT420 terminals.

I think "/etc/serial.conf" may be what you want.
