Visors have a keyboard driver running. Disable it before you open the port. There is info on the Handspring developer's site on what you need to do.
>Is 115K communication speed supported in Visors? Visor's don't have a RS232 serial port. Just a Tx and Rx pins with TTL/CMOS logic levels. You should use a RS232 interface chip between the Visor and your hardware if you plan to interface with a RS232 device. This is what the Visor serial cradle does. ----- Original Message ----- From: "Alexandre Kazantsev" <[EMAIL PROTECTED]> To: "Palm Developer Forum" <[EMAIL PROTECTED]> Sent: Friday, September 06, 2002 9:08 AM Subject: Handspring Visor and serial driver > Hi all, > > My customer wants to use my application on Handspring Visor.
