About 7 years ago I setup a Redhat system with 8 serial terminals and 8 serial printers, this is still running but I need to get another system running so the original can be taken down for maintenance. The printers are ancient Newbury data dot matrix wide carriage with 7 data bits receive 8 data bits transmit Xon/Xoff flow control. Now I remember setting the transmit and receive data bits as above but after 7 years can't remember where. Can anyone help this is making a simple job into a bit of a pain?

Thanks in advance

Serial ports are configured with the stty command, but it has been years since I last did this.
Please see man stty

Welcome to LQ!

I can see that stty allows the input speed (ispeed) and output speed (ospeed) to be set under special settings. This is how I must have done it. Will test with the new system, thanks for you help.
