Now that my TRS-80 4p is in working condition, I'd like to get some disks made. I have successfully serial booted it and run a single program over RS232.
The Apple II has a great program called "ADT" (Apple Disk Transfer) that allows you to transfer disk images over serial from a windows box to the Apple, and it writes directly to an unformatted floppy.
I know its possible to send individual files via XMODEM, but I would like to transfer entire images directly to floppy.

Does such a thing exist for the TRS-80?
 
Just out of curiosity, do you know of a link to documentation about the "serial booting" feature? I've never heard anything about that, other than perhaps some vague reference to it being "possible" to boot cassette-based 4s from a Network 3/4 controller?

Ages ago I remember there being a design out there for transferring disk images from a TRS-80 Model I to a PC using a custom *parallel* cable and a BASIC program that was short enough to reasonably type in on the Tandy side. I would love to find that again (along with the source code for the PC side) and see how hard it would be to reverse it to send an image from the PC to the Model I for writing. That's the closest I've seen to something like ADT for the Tandy I/III/4, but obviously something that depends on BASIC would be a problem for the 4P.

This is the utility I used to serial boot my 4p:

I'm running Windows 7 x64, but this utility worked fine in DosBOX /w virtual serial port redirected to a real one (USB -> Serial Adapter)

I wish I was better at programming, I'd write an ADT type program for TRS-80
 
If you had a real 5.25" drive you could make disks using an emulator, but based on your Win7 x64 that option is not realistic. You could get a kyroflux or a catweasel and use their utilities to run a 5.25" drive.
 
Another lengthy article on transfering files via serial from a PC. Crap, kb2syd corrected this. This is only once you're in LDOS. I was speed reading, trying to find another site I referenced that had the serial boot technique of the 4p but couldn't find it quickly although the link above should be good.

That's not booting from serial, that's transferring files via serial. Need a boot disk to make it happen.

That was part of the Jeff Vavasour TRS-80 Emulator. It only worked one way (Model I to PC) to transmit a ROM Image or an image of a single density diskette.
