I'd like to do some simple file-transfer between my MS-DOS box and my mac, so I decided to use kermit. I've sucessfully used it between two macs over serial lines. But I cannot get anything to happen between a mac and PC. All the settings (speed, parity, handshake, flow control, favorite liquor) are the same on the two platforms, but nothing comes accross. I have a feeling the PC kermit might be sensing lack of dtr, but don't know how to disable this. Or perhaps it's a bigend-littleend problem??? both machines work properly - I'm typing this from the MSDOS box.... anybody have any ideas??? Please reply via net mail. -JT

I have had no problems doing this with only three wires (data in/out, ground) connecting each, with no other links on the cable. Software used was locally written terminal emulators for both mac & pc, using kermit transfer. -- Graeme Moffat, Phone : +64 9 737 999 x8384 Computer Aided Design Centre, Fax : +64 9 366 0702 School of Engineering, Mail : Private Bag, Auckland, NZ University of Auckland Email : g.moffat@aukuni.ac.nz

Big-end/little-end is something else. The first step in this sort of thing, in my experience, is pin-2/pin-3: if one machine talks on pin-2, then the other one must listen on pin-2 (and talk on pin-3). Different machines do different things (the standard is not for connnections between 2 machines - it is for connections between a machine and a modem,. i.e. a DTE and a DCE). Next, come those DTR problems. If your PC want DTR high, it is possible to give it DTR from one of its other pins (I forget which one). This things are very different from one PC to another (even if they are all IBM-compatible).
