3.3.4.7 Modem Lead Signals in CLDPS Mode
The HW 86012/22 module provides a fully featured RS232 serial interface. The modem lead
signals have enhanced functionality, depending on the data mode selected, the state of
client or server configuration (SPTCPMODE resp. SPTM) and the configuration of enhanced
call control (SPECC). DTRI additionally depends on call control (SPCC) setting.

if call control is enabled activation / deactivation of
DTRI establishes / releases SWAP connection,
otherwise connection will always be established
(DTRI ignored). Connection termination is delayed
on DTRI release i.e. short DTRI changes will be
signalled to the remote DSRO signal e.g. to drop a
remote modem’s connection.
