I want to use Async under C + + Builder6. Use the TApdComPort. At compile error: E2451 Undefined symbol 'ApdComPort'
Any ideas?.

This is just a guess, since I've not touched RAD2010, but did they change the integer data type? I know the default string type was changed from ANSI strings to Unicode strings, so it wouldn't surprise me to know they changed integers from 32 bits to 64 bits. If that is the case High(Integer) would now return 9,223,372,036,854,775,807 instead of 2,147,483,647.
The reason Integer might change...

I'm trying to compile Asyncpro on RAD 2010 but I get the message **[DCC Error] OoMisc.pas(2688): E2100 Data type too large: exceeds 2 GB**
where the source code is **TOBuffer = array[0..pred(High(Integer))] of Char;.**
If anyone has knows how to solve this I would appreciate very much for guidance.

Thanks.
Yes, that's what I was assuming - but just thought I'd check that it's not something from some version with which I'm not familiar, or if someone knows it as a publically-available 3rd-party "add-on", etc...

That class doesn't appear in the APro source code. Presumably it is derived from one of the APro classes but in that case you should have inherited the source code for it too. Sorry I can't be of more help.

I've inherited some code that contains references to "**TApdRS232Stream**" - does anyone recognise that??.

That is certainly an abuse of the RS232 standard!
If you abuse the standard like that, you are doomed to be plagued by problems that result from it!

Could you not just make an adaptor that disconnects DCD at the PC?.

I have a device here, with DCD shorted to RD (don't ask). When I try to
communicate to it using AsyncPro, it hangs. Separating the lines fixes the problem, but I need it to work as-is.
Flow control is off. This same device works with a number of other programs, and HyperTerminal.
Any ideas?

Ya, i was hoping that asyncpro had that challenge solved for me :)
Ill just have to dink with it more to figure out how to get around it.
One "check" i have that runs in both modes, is if a certain packet isnt recv'd with an 8 second window it stops... as the data once connected, is basically a dump of data over and over and over.. so thats at least 1 check for connection dropped.. but...

There is no such thing as "carrier" when dealing with TCP/IP. In fact, detecting when TCP/IP connections are dropped can be a real challenge. You might try the OnTriggerStatus event. If that doesn't fire I'm not sure what to suggest.
