Gerard,
There are a couple of things you could take a look at. The "Device Drivers
and Installation Commands" shows four possible values for the CTC protocol
to be used:
protocol_no is the protocol number for CTC or ESCON. This can take the
values:
- 0 for compatibility mode (the default; used with non-Linux peers other
than OS/390 and z/OS)
- 1 for extended mode,
- 2 meaning "CTC-based tty" (this is only supported on Linux-Linux
connections),
- 3 for compatibility mode with OS/390 and z/OS.
If I were experimenting, I would probably try protocol 1 first, followed by
2, then 3.
You may also want to consider specifying escon0 and not ctc0, since you have
them defined as ESCON devices and not CTC devices. The device _name_ that
gets created is still ctc0 (oddly enough), but using escon0 in my
/etc/chandev.conf causes it to show up as channel type 0x02 instead of 0x01.
Do a "cat /proc/chandev" to see what your system thinks it is. Most likely
it is going to be 0x01. Also, when I specify the protocol type, I had to
specify the buffer size as well.
escon0,0x700,0x701,0,1
worked, but
escon0,0x700,0x701,,1
did not.
Just as a plea for "non confusing" system definitions, I would change
IODEVICE ADDRESS=(D10,001),UNITADD=01,CUNUMBR=(0D10),STADET=Y,*
PARTITION=(DEVS,PROD),UNIT=SCTC
IODEVICE ADDRESS=(D11,001),UNITADD=00,CUNUMBR=(0D10),STADET=Y,*
PARTITION=(DEVS,PROD),UNIT=SCTC
to
IODEVICE ADDRESS=(D10,002),UNITADD=00,CUNUMBR=(0D10),STADET=Y,*
PARTITION=(DEVS,PROD),UNIT=SCTC
and reverse the read-write channels on the Linux/390 end:
/etc/chandev.conf escon0,0xc21,0xc20

I'm going to be crazy with this connection, Can you explain me what's
wrong with my definition please ?
I would like to establish a session between SYST & DEVS
