Cable is okey. External device is working. Because the data is transferred between the palm and pc successfully. the data is transferred between the external device and pc successfully.
protocol is "300,e,7,1". But I couldn't transfer any data between the external device and palm. Maybe I should consider using another function group (if any) instaed of: SerOpen , SerReceive... What do you think? thanks -------Original Message------- From: Palm Developer Forum Date: 24 Temmuz 2002 Çarşamba 18:12:52 To: Palm Developer Forum Subject: Re: read serial port Does your external device use any of the control lines? - is this external device expecting a specific control line protocol or is just a plain old null modem connection Is the cable to this external device wired to properly communicate with the device?
