What you just described seems to work just fine on my system (AT w/serial port connected to an EPROM programmer). The commands that work for me are: mode com1:96,N,8,1 copy filename com1 It works just fine if there's a colon after "com1" in the copy command, too. bill frolik hp-pcd!bill Hewlett-Packard Portable Computer Division Corvallis, Oregon

The problem is that the standard IBM BIOS and device drivers must see "true" signals on the DSR and CTS inputs. If you are using a three-wire connection (transmit, recieve and ground), or if the remote device does not support these signals, you will get "Not Ready" errors. The solution is to use a fully wired cable, or at least bring through the DSR (pin 6), CTS (pin 5) and RLSD (pin 8) lines. Chances are that your remote device forces these lines true, which will make the bios happy. If it does not, then you need to wire up a quickie connector that ties those signals high. The easiest way to do this is to wire the three pins mentioned above to pins 20 (DTR) and 4 (RTS). These two signals are outputs from the PC that are always held high. Bob May hplabs!hp-pcd!bobm
