I seem to remember reading somewhere, possibly in this newsgroup, that
Applesoft basic has problems keeping up with data via the serial ports of
a //c at greater than about 1200 baud. 

Does anyone know if this is true?

I have a problem trying to input a data string into a basic program via
serial port 2 at 4800 baud. I realy did not want to resort to a machine
language sub-routine for a simple function unless necessary, but it seems 
as if the input statement in basic cannot handle the data at this rate.

Has anyone else experienced this problem and if so, is there a simple
answer?

Incidentally, a PC or compatible or a dumb terminal has no problem handling
the data string and the baud rate of the input cannot be changed.

The data format is 8 data bits, no parity, 2 stop bits, 4800 baud.

Thanks,
