I suspect that it would be just as difficult to get Laplink.exe installed on the machine as it is to get kermit.exe over there.

I have one machine, an Omnibook 300, which is one of the first completely disketteless laptops. It has a mechanism built in to 'inject' llremote.exe (a tiny laplink TSR that actually works peer-to-peer well too) into any other DOS based machine.

Digging into the dialogues in the 'remote install' program of Laplink on the Omnibook, it tells you to type the following two lines:

MODE COM1:2400,N,8,1,P

I assume that the remote end (the Omnibook 300) then seizes a console into the target system and uses some variant of 'COPY CON' to inject the laplink remote access TSR program.

Can't the plain old DOS copy command be used in the same fashion, i.e.:

MODE COM1:9600,N,8,1,P
COPY COM1 filename.exe

entered at the 'receiving' system (at the right points in time)

A null modem connection would be established, and the commands:

MODE COM1:9600,N,8,1,P
COPY filename.exe COM1

would be issued from the machine 'sending' the file.

Please update me and/or correct me if someone else on the list has more experience with this.

Haven't done a lot of this kind of stuff in ages. I converted over from CP/M to DOS back in the day over a three-wire interface. I used to say 'the universal file transfer format is a piece of copper wire.'
