I have read about this problem.  It happens with some implementations
of rz on unix systems.  You can use rb and ymodem instead.

The max port speed on a gs is not 19200.  ;-)

For serial connections to RS232 devices like modems, the max port
speed is 56k.  On ProTERM 3.1, check the baud rate settings.  That
should verify the max speed is 56k.  You may be thinking of the
control panel for the IIGS...it says 19200 is max because it does not
know better (crazy folks at Apple thought back in 1986 that nobody
would use faster than 19200, so they put that as max setting EVEN
THOUGH THE SERIAL CHIP CAN HANDLE MUCH FASTER).
But programs like ProTERM that have their OWN serial port drivers
can use the chip at higher speeds like 56k.  I use 56k to communicate
with my printer all the time.

For AppleTalk, the serial ports lock at 230k.  That's 230,000!  A
far cry from 19200.
