In early versions on Unix I could put the following lines in the /etc/rc file to slow down the flow of data to a serial printer.
stty ctsflow ixon 9600 </dev/tty##
(were ## is the port # where the printer is connected)
In Unix 3.2 V5.01 this causes the system to lock on boot when loading print services.
Use to work on earlier versions, or am I doing something wrong?
I have slowed the baud rate to 1200 and I can print long reports, but takes forever.
I need to get the speed back without loss of data.
