We're having a disagreement about how 'standard' use of hardware flow control
(that is, RTS-CTS signalling) is for serial communications. I know that the
the RS232 'standard' is not really a standard (in the sense of having all 
details fully specified), but how off-the-wall is use of hardware flow control?

We need to be able to operate to 115 Kbaud and transfer binary data. Does
anyone know whether packages that operate at this speed and do binary transfer
(LapLink and Commute come to mind as examples) use hardware flow control?
Do any packages use xon/xoff to do this?

The statement has been made that many communication packages commonly used on 
the PC have no provision for dealing with hardware flow control. How true is 
this? Another statement was made that QuickBASIC has no provision for using
hardware flow control. I don't use BASIC; is this true?

Thanks for any facts you can give me.
