I had to move to the new serial manager for Palm OS 3.5.2 Just one thing, your serial receive TimeOut is set to 1 sec, and I see no loop inside this routine.
So, don't you think that it might just "miss" the data ? Do you use the cradle to transfer data from PC to Palm ? Cordialement, Agus Silas BST Technologies T. (+33) 5 57 80 16 03 F.

Can you communicate with your device using the Windows terminal program and cable you currently have? If not, you need to fix that first. ----- Original Message ----- From: "Akhil Bhandari" <[EMAIL PROTECTED]> To: "Palm Developer Forum" <[EMAIL PROTECTED]> Sent: Wednesday, August 28, 2002 12:34 AM Subject: RE: Help with basic serial communication > Try it with new serial manager, as this solved our > problem. > > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED]]On > Behalf Of Sean > Rogers > Sent: Wednesday, August 28, 2002 7:11 AM > To: Palm Developer Forum > Subject: Help with basic serial communication > > > I've been struggling with this for a while, any help is > greatly appreciated. > > I've got an external device that just sends some bytes > in through the serial > port.
