In my exuberance to provide assistance, I missed the unit address. I have
not seen it define like that before but cannot think of any reason that it
should not work since it is the unit address that must match. Does your
CTC show up when you enter IFCONFIG? Any other error messages? There is
not much to go on.

Subject: RE : ESCON CTC between two LPAR LINUX (SLES 2.4.7)
Hello Peter,
I don't understand your answer,
D10 (unitadd=01) chpid(99 CNC) is the read device and point to c20
(unitadd=00) chpid(98 CTC)
D11 (unitadd=00) chpid(99 CNC) is the write device and point to c21
(unitadd=01) chpid(98 CTC)
I believed that the crossing was done thru the unitadd parameter, wasn't
it?
Where do you see my mistake?
I've got no problem between z/OS and Linux where the read or write
option is controlled with the TCPIP parameter (0 = read, 1 = write).
Have you got a sample?
Thanks in advance.

I have CTCs working fine between a z/OS system and Linux. What I see
that
is most glaring is that you have the read channel connected to a read
channel and a write channel connected to a write channel. Try reversing
the UCB address on one of your CTC definitions. The read channel must
connect to a write channel and a write channel must connect to a read
channel.
I also assume that everything else is configured correctly in the
rc.config. Try the ifconfig command to check the status. Let me know how
it goes. Good luck.

I'm going to be crazy with this connection, Can you explain me what's
