HI I want to send some data from my z80 micro pc to my home pc. I want to save this on my A: drive floppy. Can I do it? What is the command from ms-dos to save on A: drive? I'm sending the data via an 8251 USART to serial port. Appreciate any help.
If it's a dos machine then you could do "copy com1 a:\filename.txt". I can't remember how to terminate the transmission. I think it may be terminated when a ctrl-z is received.

He may be trying to get a copy of GW or QB on the machine and only has a dos disk. Unfortunately, the above wont work as it's only good for text files.

That frightens me. Lately I've been noticing that computers don't have floppy drives any more, and I *really* need to get my floppies out of storage and use one of my old machines to try to save as much as I can.
Back to the topic: I thought the OP was asking how to send a file to the PC from the Z80 and cause it to be saved to the a: drive, without any comms software running on the PC. I am aware of no way to do that; there must be some software running on the PC to accept the connection, read the data, and write it out to the disc.

It might be worth you buying a USB floppy drive, common practice for laptop owners for many years.

Don't be frightened. Every mainboard still comes with a floppy connector. I regularly build machines (for other people) without floppy drives. I have a drive on the shelf with cable that I plug in and run hanging out the side temporarily for whenever I need a floppy in a machine. When done, unplug, change the BIOS setting back and put the side cover back on. 99% of users do not need a floppy drive, but I do occasionally.
