App LINK SetRemoteBaud
Syscall index: 0x1397
Function signature: int App_LINK_SetRemoteBaud(void)
Changes the current communication settings in both the local and connected device to 115200 baud, no parity and one stop bit.
The timeout in milliseconds for data reception by the Link app.
This syscall does the following:
- Sends a Protocol 7.00 packet to the connected device, with type 1 (Command) and subtype "02" (Set link settings), and the 115200 baud, no parity and 1 stop bit settings encoded in the packet's data fields (see fxReverse for more information);
- Closes the serial port (the connected device should do the same, or perhaps adjusts settings on-the-fly with Serial_Open);
- Opens the serial port with 115200 baud, no parity, 1 stop bit just like the remote calculator was requested to do.
During a normal, OS initiated communication, this procedure is performed after reading the remote calculator's model with App_LINK_GetDeviceInfo to determine if the high-speed 115200 bps mode is supported.
For more information on Protocol 7.00, see fxReverse.pdf.
