Set the same number of transmission attempts for
the communication partner as for the CP. Check for
malfunction on partner device, possibly by using an
interface test device interconnected in the data link.
Correction at the partner is necessary.
The partner has switched the DSR or CTS signal to
"OFF" before or during a transmission.
Check the partner's control of the RS 232C
accompanying signals.
Remedy
Check that the partner has the desired data area and
that it is big enough, or check the parameters of the
