I have a serial cable and can get the machines talking to each other. I'm
doing the following, on the QL
copy_n mdv1_filename to ser1hz
on the PC
copy com1 filename
This appears to work ok for text-based files, which I can then open up and
load in Q-Emulator. However, for binary
files I am having problems in that the transfer never completes - the PC
reports the transfer as complete, but the
QL is still sending, and I end up with only part of the file on the PC. I
think what's going on is that there's a
combination of characters within the file body that is being interpreted
as an EOF (ctrl-z).
Does anyone have any suggestions as to how best I can get my files copied
across. I will also need to get some
files from the PC to the QL (i.e. I haven't tried yet), are there any
pitfalls or tips to getting that to work.
Many thanks for any help.
I'm not sure about the eact problem you decided regarding possible false
EOF, but you should beware of the risk of losing the executable file header
when a binary (executable) file header gets saved on the PC hard disk.
QemuLator can handle such files in its own directories as it stores the
header separate to the executable.
One possible way of working around this is to make a note of the executable
program file's length and dataspace on the QL then you stand a chance of
being able to restore these in qemulator - lbytes the program file into the
common heap, then SEXEC filename$,start,length,dataspace
If you had a floppy disk drive on the QL and PC, this would have been the
easiest way as Qemulator can read QL floppy disks.
There are a couple of pages on my website regarding transfer, but it looks
like you've done the hard work already, just need to find a way to work
around the ctrl-z problem.
