writing stuff like ctrl+z on a port

stormbringer · 10-05-2002, 01:56 PM

hi everybody

i am opening my modem port with fopen and the write at commands to it using fprintf. however. to terminate a certain line of text i need to send a ctrl+z (that means that if i do it manualy in a terminal i enter the commandline and the text and then press ctrl-z). how can i write a control-z on the port? i thougt that is a special escape sequence or i could do anything with the ascii table, but i didn't find anything.

thank you for helping

where can i get a table what a number a combination is, or is this based on the ascii table?

i don't think i get you right....
i press the control key (or the alt or the shift key) and then another key. so there should be a number that signifies that the control key is pressed down and then the other key i.e. Z ist pressed and then both are released.
is SUB the number that means control key pressed?

what is the value for ctrl-a or ctrl-c or whatever? how can i determine the value of a certain combination?
i'm sorry, i'm really trying to understand....

ok, i started thinking about it and got the folowing: control sequences start from 001 to 026 (ctrl-a to ctrl-z)
alt sequences always start wit 000 and then another number which identifyes the second key pressed? (ibm scan codes)
is that right?
