Minicom For Linux

Mincom should be set up with:

• 1152 bps
• 8 data bits
• no parity
• 1 stop bit
• no flow control

This can be done when minicom comes up by typing:

    minicom -s 

and entering

• Serial port setup
menu
• type "A" and edit serial device to /dev/ttyS0 for COM1
• type "E" to enter Bps/par/Bits
submenu
• type "I" for 115200 baud then <return>
• type "F" until hardware flow control is "No"
• type "G" until software flow control is "No"
• <enter> to leave menu             
• modem and dialing
menu
• type "A" and edit Init String to make it blank then <enter>
• <enter> to leave menu
• save setup as dfl menu
• exit menu

You should end up with a minirc.dfl file (perhaps in /etc - check minicom –h) that looks like:

    # Machine-generated file - use "minicom -s" to change parameters.
    pr port             /dev/ttyS0
    pu baudrate         115200
    pu bits             8
    pu parity           N
    pu stopbits         1
    pu minit            
    pu rtscts           No 

Make sure the /dev/ttyS0 has read and write permissions for everyone.

Here are a few key minicom commands.
