Because this is what you serial  driver  reports  about  the  current
state of these pins?

You already did. The relevant lines from the ~/.kermrc file are:

	set carrier-watch off
	set handshake none
	set flow-control none

To verify, type "show comm" at the kermit prompt:

	Kermit>show comm

	Communications Parameters:
	 Line: /dev/ttyS1, speed: 115200, mode: local, modem: generic
	 Parity: none, stop-bits: (default) (8N1)
	 Duplex: full, flow: none, handshake: none
	 Carrier-watch: off, close-on-disconnect: off
	 Lockfile: /var/lock/LCK..ttyS1
	 Terminal bytesize: 8, escape character: 28 (^\)

The relevant part here is the "flow: none", "handshake: none" and
"Carrier-watch: off" entries.

Best regards,

Wolfgang Denk
