Minicom offline but Uart registers working
I am using a driver for a multiport serial card - PCI based in my PC.I am able to do a #insmod and also I am able to access the internal registers
like SPR( Scratch pad register),ISR( Interrupt service register ),LSR(Line status register ) etc ..Performing read/write operations using the driver
give desired results as per the spec - XR16L784,but when I try to open minicom for a simple loopback test the minicom is offline
following is the op on my terminal
PLEASE TAKE A LOOK AT THE ATTACHED TEXT FILE FOR THE COMMAND OUTPUTS SINCE I AM NOT ABLE TO POST THIS

Are you asking how to tell minicom to use a specific device/port? If so, then in minicom:
1. Press Ctrl+A to open the configuration menu
2. Arrow down to Serial port setup and press Enter
3. In the Change which setting? window, press A to move the cursor to the Serial Device entry
4. Backspace to delete the existing device and enter your desired device
5. Press Enter when done
You can optionally save it as the default device, or you can save it to a separate config file (it will be /etc/minirc.YOUR-NAME).
