Yes, you can make the Palm serial port spit out data and ignore
handshaking - very easily. You could do the same thing with the IR
port, but it would take a bit more work.
Likewise, you could sit and listen for data on the serial port, etc.
But, with IR, you would do well to build your app on top of IrDA. The
communication link itself is not terribly reliable. IrDA LAP gives you
error detection, collision detection, retry, etc. Mechanisms that you
would have to build yourself otherwise.
Good Luck,

Subject: Can 1-way non-link transfer data?
I've been lurking and learning for the last couple of weeks. Is it
possible
to make an application that does not set up a 2-way link, that still
sends
the data one way. The simplified scenarios are:
1. Case 1: Data from PC to Palm. PC with serial port controlled
infrared
transmitter, Palm with serial connection to an infrared to RS-232
converter.
(not the built-in IRDA interface on my Palm III)
2. Case 2: Data from Palm to PC. Palm with serial connection to
infrared
blaster (not the built-in IRDA interface), with a special IR to RS-232
converter on the PC.
The infrared link is just an example for this question. It could be
replaced by and RF (one way only) link, or even just a 2-wire RS-232
(either
transmit only, or receive only) physical connection. The question I am
trying to answer is: Can the provided development tools support a
strictly
one-way (no handshaking) data transfer? Can this transfer happen to go
both
ways (using 2 separate configurations)? I don't want to sound like I'm
repeating myself repeating myself, but answers I've gotten from others
ignored startup handshaking before the data transfer.
