I am having a bit of a problem with my serial port I hope someone can help me with. I tried to hook a terminal up to the serial port and run it through the AUX device. I know the terminal works because I can use it with a HAYES modem with no problems. (Also the cables are good.) I can also use the modem with the AMIGA through the serial port. I make sure the AUX is mounted, then type, "newcli AUX:" as it says in the 1.3 manual. I make sure the baud rates and such is set right. But nothing happens with the terminal. No commands entered, no echo, Zip! I believe another problem is related -- I also get no luck hooking up a serial interfaced (RS-232) PaintJet to the serial port. I make the PaintJet pick in preferences and select the "serial" gadget. I have both the AMIGA and the paintjet set for XON/XOFF handshaking. (I tried No handshake too) So I figured I must be doing something wrong. Thanks for any help, Dave S.

No commands entered, no echo, Zip! > You probably need to get a "null modem" style cable, one that swaps RS232 transmit and receive lines (2 and 3). In the jargon of the RS232 spec, your modem is "DCE" (Data Communications Equipment) and your terminal is "DTE" (Data Terminal Equipment). DTE will connect to DCE with a straight through cable, so hooking up your modem to your terminal works fine. Your Amiga's serial port is a DTE device, so hooking up the modem to the Amiga is again no problem with a straight through cable. When you try to hook up the terminal though, you are connecting DTE to DTE, so you need to swap lines 2 and 3 in your cable in order to ensure the transmit line of one device goes to the receive line of the other. If all this seems obscure, just ask your dealer for a "null modem" cable. -- Howard Owen, Computer Systems Manager internet: hbo@nobbs.ucsb.edu Physics Computer Services BITNET: HBO@SBITP.BITNET University of California, Santa Barbara HEPNET/SPAN: SBPHY::HBO "I am not a pay TV service!" 805-961-8366 (work)

I don't remember the pin numbers, but with rs232 you have a "send" line and a "receive" line. Normally your amiga, or your terminal, writes data to one, and the modem writes data to the other. With the terminal connected directly to the computer, both are writing to the "send" line (which no one is reading), and both are reading the "receive" line (which no one is writing to). The null modem swaps the lines in the middle so what one side writes can be read on the other end. -don perley

The one I'm using right now, I got for use with Harald Koch's UUCP and is (or is based on) one that was posted to the net a while back by Steve Drew. It works better than the standard 1.3 handler for just such stuff as running a cli from a terminal. I hope that suggestion has at least some relevance to your problem. -- Hugh D.
