Wayne is developing a custom keypad and he has one for the 10-pin serial interface that works. He's trying to develop a similar keypad for the 16-pin serial interface. The serial manager really doesn't have anything to do with it. Wayne is watching the signals on an oscilloscope and when he asserts request to send on his end he can see the PDA assert clear to send. However when Wayne sends data it seems to go into never-never-land. Wayne is watching for the data in memo pad and it doesn't appear. What Wayne needs at this point is someone who is very familiar with the 16-pin serial interface to tell him what else he needs to do signal-wise. We're stumped at this point and need some help from Palm's logic designers. regards, Dave Mottorn -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Dave Lippincott Sent: Monday, July 21, 2003 2:56 PM To: Palm Developer Forum Subject: Re: Hardware 10 pin to 16 pin serial interface migration If you used the new serial manager with your '10-pin' software, there should be no changes in your serial code to work on newer units. ----- Original Message ----- From: "Wayne Pietluck" <[EMAIL PROTECTED]> To: "Palm Developer Forum" <[EMAIL PROTECTED]> Sent: Monday, July 21, 2003 2:43 PM Subject: Hardware 10 pin to 16 pin serial interface migration > How do I migrate a 10 pin serial interface to the new 16 pin serial > interface? > > Obviously the 10 pin docking connector must change to a 16 pin version. > > I've remapped the signals from the 10 pin to the 16 pin as follows: > > PALM 10 PALM 16 > 1.
