CHAPTER 25
Modem Setup Service
Dening a Modem Setup 25-7
Setting the Fax Prole Option 25
The fax prole 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 dened, then the fax send and receive speeds are not
restricted.
Table 25-1 Summary of conguration string usage
Conguration string When used
kConfigStrNoEC
The default conguration used for data
connections when kDirectConnectOnly is
nil. Also used for FAX connections. See
“The No Error Control Conguration String”
(page 22-7) in Newton Programmers Reference
for an example.
kConfigStrECOnly
Used for data connections that require error
correction. This conguration string is used
only if requested by an application. The
constant kSupportsEC must be true for this
conguration string to be used. See “The Error
Control Conguration String” (page 22-8) in
Newton Programmers Reference for an example.
kConfigStrECAndFallback
Used for data connections that allow error
correction, but that can fall back to non-error-
corrected mode. This conguration string is
used only if requested by an application. See
“The Error Control with Fallback Conguration
String” (page 22-9) in Newton Programmers
Reference for an example.
kConfigStrDirectConnect
The default conguration used for data
connections when kDirectConnectOnly is
true. See “The Direct Connect Configuration
String” (page 22-9) in Newton Programmers
Reference for an example.
