Setting the Modem Profile Option

25

This modem profile option describes the modem characteristics, to be used by the
modem controller. Here is an example:

constant kSupportsEC

:= true;

constant kSupportsLCS

:= nil;

constant kDirectConnectOnly:= nil;
constant kConnectSpeeds

:= '[300, 1200, 2400, 4800,

7200, 9600, 12000, 14400];

constant kConfigSpeed

:= 38400;

constant kCommandTimeout

:= 2000;

constant kMaxCharsPerLine

:= 40;

constant kInterCmdDelay

:= 25;

constant kModemIDString

:= "unknown";

constant kConfigStrNoEC

:=

"ATE0&A0&B1&C1&H1&M0S12=12 ";

constant kConfigStrECOnly

:=

"ATE0&A0&B1&C1&H1&M5S12=12 ";

constant kConfigStrECAndFallbac

:=

"ATE0&A0&B1&C1&H1&M4S12=12 ";

constant kConfigStrDirectConnec

:=

"ATE0&A0&B0&C1&H0&M0S12=12 ";

For detailed descriptions of these constants, see "Modem Setup Profile Constants"
(page 22-4) in Newton Programmer's Reference. For more information about the
modem preferences option, see "Modem Profile Option" (page 21-38) in Newton
Programmer's Reference.

When the modem tool establishes communication with a modem through an
endpoint, the tool normally sends a configuration string to the modem (as long as

kUseConfigString

is

true

). Several configuration strings are defined in a

typical modem profile; the one that is sent depends on the type of connection
requested and other parameters set in the modem profile. Table 25-1 summarizes
when each kind of configuration string is used:
