Microvax connecting from console (MMJ) to DB25(female) DCE port

...usually. I've seen two things which could break this. (1) Some devices require some of the modem control signals in order to operate at all. Hooking up just TxD, RxD, and GND won't be enough in such cases. (2) I've even seen one device which powers down its transmitter unless it sees at least one input pin being driven. This is extremely annoying, because when you go in with a meter (or lights) to figure out which pins are being driven you find that none of them are. It also means that you can't test it by just shorting TxD to RxD even if the software is configured to ignore modem control signals. Mercifully, such devices seem to be rare; I've seen only one, out of all the serial ports I've dealt with, as far as I know. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
