The terminal driver uses various symbolics for its operations. The values for these symbolics can be found in the I/O Drivers Reference Manual, Chapter 2, with a couple of exceptions. To find the values of the QIO subfunction symbolics, type HELP TTSYM TF. To find the values of the terminal speed symbolics, type HELP TTSYM S. All terminal driver symbolics are defined in the module TTSYM$ in the system macro library, usually located in LB:[1,1]. You can get a listing of them by executing the command "LBR TTSYM=LB:[1,1]RSXMAC.SML/EX:TTSYM$" and printing out the resulting file, TTSYM.MAC. 2 S.
