Did I get the right device? USB-Serial

[wdmagic]

thanks, i will be using VB.net to build the interface program, but I was wondering just to test it out.. I remember back in the days of DOS, you could do a command like

c:\12345678 >com1 ???
or
c:\copy test.txt >com1

something like that, I cant remember it exactly, but you could send a text string or file directly to a com port or lpt port. can you still do that?

also is it possible to send a large number of bits, say 32,48,64 and have it store them in a set of variables, for example

MYBYTE0 VAR BYTE
MYBYTE1 VAR BYTE
MYWORD0 VAR WORD
MYWORD1 VAR WORD

LOOPME:
SerialIN????
code to break up string in pieces and store in variables
GOTO LOOPME

my textbox on PC has 48 "1 & 0's" no spaces to be sent as an example

Hi Chris,
Can't help with the command line interface to the COM-port, never seen that before. Doing serial coms in VB.net using the supplied serial port object is quite easy though. Just beware that Microsoft removed the serial port object from VB when they introduced .net and put it back in some later version. I believe all the Express versions have it if that's what you're using. It's been a long time since I played with VB.

On the PIC side there's no problem to receive "any" number of bytes. HSERIN can split the bytes up properly as it receives them or, if you're using an interrupt driven routine you can store the data in an array and split them up when everything is in. It all depends on how the data is formated, high or low byte first etc.
