So basically the jumped pins are to facilitate software handshaking, and this happens by having pin 1,4,6 in 9 Pin sockect and 6,8,20 on the 25 pin connect to themselves on either end, and nothing else, or 1,4,6 connect to 6,8 & 20???
Matter of interest does hardware handshaking happen if theses aren't jumped, or is it only on certain machines.
O-mate controls and download from machine no problem but won't unload, alarmed out #087 "input is not interrupted after 10 characters read".... Thats handshaking right??? |
Yes, the handshaking pins are only jumpered out at each end, All this really does is making sure the hardware handshake is happy, wether or not it is enabled. This leaves a choice of either software HS or non at all.
Hardware HS can only occur, if instead of being jumpered they are connected in the correct fashion to either end.
If I recall, that #087 may be because a parameter is not set regarding a line feed being/or not being sent.
I will have to look up some of my notes as I recall this occuring on a 0P system once.
