cat > opt/minicom/etc/rc/S99minicom
#!/bin/sh
echo "Press a key for minicom..."
read x
minicom -s
Press Ctrl+D here.

In a real device, you would create a minicom configuration file and let it start directly.You also

it. If all goes well, you'll get the following message:
Press a key for minicom...
29. Pressing a key should start the Minicom program. If you connect a serial modem to your serial port,
you should be able to dial out.You may get a couple of errors during the boot process—one about
