Defining a Modem Setup

Setting the Fax Profile Option

25

The fax profile option describes the fax characteristics to be used by the fax tool.
Here is an example:

constant kTransmitDataMod

:=

kV21Ch2Mod + KV27Ter24Mod+ kV27Ter48Mod;

constant kReceiveDataMod:=

kV21Ch2Mod + KV27Ter24Mod + kV27Ter48Mod;

constant kServiceClass

:=

kModemFaxClass1 + kModemFaxClass2;

This example limits the faxing to 4800 bps for both send and receive messages. If
neither of these constants is defined, then the fax send and receive speeds are not
restricted.

Summary of configuration string usage

kConfigStrNoEC

The default configuration used for data
connections when

kDirectConnectOnly

is

nil

. Also used for FAX connections. See

"The No Error Control Configuration String"
(page 22-7) in Newton Programmer's Reference
for an example.

kConfigStrECOnly

Used for data connections that require error
correction. This configuration string is used
only if requested by an application. The
constant

kSupportsEC

must be

true

for this

configuration string to be used. See "The Error
Control Configuration String" (page 22-8) in
Newton Programmer's Reference for an example.

kConfigStrECAndFallback

Used for data connections that allow error
correction, but that can fall back to non-error-
corrected mode. This configuration string is
used only if requested by an application. See
"The Error Control with Fallback Configuration
String" (page 22-9) in Newton Programmer's
Reference for an example.

kConfigStrDirectConnect

The default configuration used for data
connections when

kDirectConnectOnly

is

true

. See "The Direct Connect Configuration

String" (page 22-9) in Newton Programmer's
Reference for an example.
