ati -- auto-recognizes baud rates and modem model

Synopsis

ati [-s setup] [-q] [-p] devicename
ati [-s setup] [-q] [-b baud] [-i atiprobe] devicename

Description

ati auto-recognizes baud rates and modem model. ati sends out a known ATI command at a range of speeds and reports back which speeds the modem works at. ati also sends out the full range of ATI commands and compares the modem replies with the database to find the best match. ati normally probes ATI0 to ATI9 unless the -i option is set. ati is found in /usr/lib/uucp.

Options

The following options are available:

-b baud: Baud rate to use. The default is 9600.
-i atiprobe: ATI number to probe.
-p: Probe for baud rates.
-q: Quiet mode.
-s setup: String to use for the modem. The default is ATE0Q0V1M0L0.

If no options are set, ati sends ATI commands to the modem. It reports what type of modem was autodetected. For example:

# /usr/lib/uucp/ati /dev/term/01m Sending ATI1

The following modem(s) are matching the autodetection: Hayes_Accura_56K_Ext_Speakerphone_Modem_5670

If the -b option is set, ati probes the modem using the baud rate specified. It reports what type of modem was autodetected. For example:

   # /usr/lib/uucp/ati -b 14400 /dev/term/01m
   The following modem(s) are matching the autodetection:
   Hayes_Accura_56K_Ext_Speakerphone_Modem_5670

If the -i option is set, ati probes the modem using the ATI number specified. For example:

# /usr/lib/uucp/ati -i 3 /dev/term/01m Probing ATI3: OK

V1.120HZ-K56_DLS

If the -p option is set, ati probes the modem to find out what baud rates are supported. It produces a message on the screen saying what baud rate it is trying and then reports what baud rates the modem supports. For example:

# /usr/lib/uucp/ati -p /dev/term/01m Trying 2400 bauds

# /usr/lib/uucp/ati -p /dev/term/01m Bauds: 1200, 4800, 9600, 14400, 19200, 38400, 57600, 76800, 115200

If the -s option is set, ati probes the modem using the string specified. For example:

   # /usr/lib/uucp/ati -s ATE0Q0V1M0L0 /dev/term/01m
   The following modem(s) are matching the autodetection:
   Hayes_Accura_56K_Ext_Speakerphone_Modem_5670
