Smartmodem 2400, V-series 9600 or compatible

The Hayes 2400 and V-series 9600 Smartmodem or AT-compatible modems are supported and are configured automatically when you use the dialer entries or dialer programs supplied with the SCO OpenServer distribution. If you are using an unsupported dialer (one brought from elsewhere or written yourself), and you plan to use it for a dial-in line, be sure that you use the following settings:

AT&f

fetches factory configuration

ATT

is tone dialing

ATl0

is low speaker volume

AT&d2

sets dtr ``2'': goes on hook when dtr drops

AT&c1

sets dcd ``1'': dcd tracks remote carrier

ATs0=1

answers phone after one ring (AA light should come on)

ATs2=128

disables modem escape sequence

ATe0

does not echo (modem no longer echoes what is sent to it)

ATq1

is quiet mode (modem does not respond with ``OK'' after this command or any that follow)

AT&w

saves settings in non-volatile memory. If you do not want to save the settings, you do not have to enter this command.
