DSR flow control is indeed available, it's just not the default. To change
flow control, as well as any of the other serial device parameters, use
the setserial program from the CLI. Typing "setserial 0" will list all the
settable parameters, a perusal of serial.h or serial.i (in the ROM Kernel
manual and elsewhere) will let you know the options available and the
settings to use. Setserial is in the public domain, available from the 
Fred Fish service, and (hopefully) your dealer. Typing "setserial 10 x84"
will disable xON/xOFF flow control AND enable DSR flow control (we call
it "7-wire protocol"). keep on slippin', tomp.
