[vcf-midatlantic] Stupid CP/M question

All — I just built myself a CompuPro Z80 system out some of my spare boards. It boots CP/M from one of the Maslin 8” disk images. To facilitate getting other programs onto the disk, I want to use XMODEM from Marty Eberhard. It compiles with CP/M ASM which is good, but what’s the best way of getting the source file onto the disk? It’s not clear if the CBIOS has code for a separate PUN/RDR port. I was thinking of using ED and then, using HyperTerminal, paste the source into the ED screen and save it. I looked at the manual for ED and it’s not clear to me if I can actually do that, so I wanted to ask the group if that’s a good way or if there’s something better. Thanks!
