Do you get the "Serial Line Error" message just once, or continuously? Make sure you are using the latest version of Online, which is 1.5. I improved the error handling code to report errors more specifically. FWIW, you will get a "Timeout" message with the Palm clip on modem every time you open the serial port with it connected. It happens once and then you are ok. The reason is that SrmReceiveCheck says there is a byte available when the port is first openened, even though there isn't. You then go to read it, but nothing is there and you time out (or hang if you pass in -1 for a timeout to the read call!). I think most apps just ignore the error, so it didn't matter (unless you are thorough and error check every call you make).
