StrongARM Serial Handshaking

Hello,
So is it safe to say that the StrongARM UART doesn't support CTS?
What is ADS's method of ensuring integrity during serial communications?
Hi Rick. You are correct. ADS implements hardware handshaking on the serial ports using StrongARM GPIOs. For example, section 3.7.7 of the GC Plus users manual (rev. B) explains that the GC Plus uses GPIO14-19 to implement the CTS and RTS signals.

Topic 410 discusses two different styles of how handshaking is implemented in Windows CE. You might try using the ADS COMTERM application, which implements both the CE "Toggle" (EIA/TIA-232C) and "Handshake" (EIA/TIA-232E) flow control modes. Source code is included.

I hope this helps!
