BOCA PRO16 Reference Guide
When V.25bis mode is selected, your modem will automatically answer
incoming calls after one ring – the setting of S Register 0 is ignored when
V.25bis mode is selected. The communications standard used by the
modem in its attempt to connect with a calling modem is determined the
B command.
If the phone does ring, the modem will issue an INC message to indicate
an incoming call has been detected and will wait the number of seconds
defined by S Register 71. S Register 71 allows you to ignore a call by
issuing a DIC command before the number of seconds defined by S
Register 71 is reached. Thus, if S Register 71 is set to 10, you have 10
seconds after a call is detected to issue a DIC command; if you do not
issue the DIC command within 10 seconds, your modem will attempt to
connect to the calling modem.
FIf you issue the DIC command but then want to answer the call, issue
the CIC command. The CIC command will cause your modem to
answer a call after the DIC command has been issued.
The modem will then go on line, transmit an answer tone, and attempt
to connect to the calling modem using the communications standard
selected by the B command.
As soon as a connection is established, the modem will send a CXN
message to your computer and enter on-line state in answer mode.

mand. Refer to the chapter titled ‘Getting Started’ for details of how the
