H89 as serial terminal

Yes, there are 2 ways to do it -- hardware and software The H89 is acutally a computer and a serial terminal in the same box, communicating via a very short RS232 cable. The terminal, which is actually an H19, has an ANSI mode which is close to being a VT100 IIRC. The hardware solution is to disconnect the internal serial cable from the termianl logic PCB (the rearmost vertical PCB in the machine) and replace it with one of the cables that goes to a DB25 connector on the back (these cables are normally connected to the serial port PCB plugged into the computer mainboard, just in front of the terminal logic PCB). The cables have a Molex 0.1" pitch SIL connector on the end, and fortunately, the pinout of all the internal serial connectors (terminal logic PCB, computer 'console port', serial port PCB) is the same. The software solution is to write a little program that transfers characters between the computer's console port and one of the other serial ports. This will then make the computer section appear as a transparent link between the terminal and the outside world. -tony
