wm6下 如何修改GPRS的拨号连接默认设置

GPRS模块的工作频率是115200，但是建立拨号连接后么查看HKEY_CURRENT_USER\Comm\RasBook\下的配置，始终是4B00（115200）， 怎么修改让建立连接是的默认baudrate是115200.

建立GPRS拨号连接后，可以通过PHM Registry Editor，修改 HKEY_CURRENT_USER > Comm > RasBook > 拨号连接名/DevCfg中的baudrate来修改， 有没一种办法可以让建立拨号连接时的默认baudrate是115200.  

Then choose the DevCfg key

In the Value data window you'll see several rows of 2 digit alphanumerics, like this:

20 00 00  00 78 00 00 00 10 02 00
00 00 4B 00 00 00 00 08 00 00 00
00 00 49  00 47 00 47 00 45 00 54  and so forth

you'll change two entries (that I highlighted in red) in the second row

change the 4B to C2
change the 00 next to it to 01

the second row should look like this:
00 00 C2 01 00 00 00 08 00 00 00

I tested this out on both pocket pcs and this changed the baud rate from 19200 to 115200 on both devices.

GPRS模块的baudrate是115200。在WM60下，建立拨号连接后，拨号配置的baudrate是19200（可以查看HKEY_CURRENT_USER\Comm\RasBook\下的配置）， 怎么修改让建立连接是的默认baudrate是115200.

修改platform.reg文件，建立一个baudrate 为115200，拨号连接名位GPRS的拨号连接 如下

不明白楼主想做什么。

只有CSD拨号才有波特率的概念，GPRS跟波特率没有关系，也没有设置项。你所说的“模块工作频率是115200”是一种不准确的说法，这应该指的是模块的串口速率，是数据在串口上的传输速度，跟你建立的GPRS连接没有关系。

#10

GPRS与串口的连接也需要工种频率的，需要与串口工作频率一置。GPRS模块的波特率可以用AT命令设置，而楼主想更改连接中的波特率的与模块一置，可以用两种方法，一，你写个程序调用函数改，二、重新建立个连接吧。关于注册表中的那一堆16进制代码还没分析过，那部分代表什么。不如重新再建立一个拨号连接。
