I am building an app which uses the serial port to interface to a simple, non-powered device which outputs pulses at a low frequency (less than 20Hz). On the Palm Vx and m100 that I have done my initial development on, it works to use a serial cable which uses only the RTS and RXD pins. It also works to attach these two inputs to the Palm serial HotSync cables.
Last week, I started some "compatibility testing" and bought a Visor Deluxe and a Clie SJ20, as well as serial HotSync cables for each. I can't get either of them to input the serial pulses (using the inputs attached to the HotSync cables), even though the serial HotSync works for both. After researching the Visor, I can see that I need to supply power, and am trying to find a new cable that will do that. Do I need to do the same thing for the Clie? On the surface, my experience contradicts Dave's statement, since I can do the serial HotSync. As always, thank you for any assistance.

Are you using a Sony serial cable or your own? The reason I ask it that the Clie hand helds do not have a RS232 line driver. They output TTL logic levels and need a line driver chip to be RS232 compatible. If you can get your SL10 to perform a serial Hotsync, you should be able to talk to it with HyperTerminal. Also double check the port geometry on the PC and Clie (baud, stop bits, parity, etc) ----- Original Message ----- From: "Rangababu, TNV (IndSys)" <[EMAIL PROTECTED]> To: "Palm Developer Forum" <[EMAIL PROTECTED]> Sent: Friday, February 07, 2003 7:24 AM Subject: Serial comm problem in Sony Clie (PEG-SL10). > Hi All, > I have one Sony Clie (PEG-SL10) device with OS 4.1 and also have a > M125 Palm with OS 4.0.
