The lack of flow control in the BIOS coupled with the default baudrate of 115200 makes the serial comms problematic.

With TerraTerm I can only get the system to sort off function if I set the inter character delay to ~ 250 mS and the eol delay to ~ 350 mS.
Putty sends the characters more slowly but if I attempt to send a file or paste text into the terminal is soon overruns the input buffer.

How about a BIOS fix for Flow control ideally with options for hardware (RTS/CTS and DTR/DSR), XON/XOFF, and none.

It would also be helpful to make the baudrate configurable.

I have got my Z80-MBC2 running your UCSD port. I can create additional volumes by copying one of the existing volumes, using Filer Zero to empty the copy fine. But how do I transfer files into the system given that it does not have a floppy interface nor is there either a Kermit nor an Xmodem for the MBC2 included in the build set?

The editor does not accept CTRL/C as ETX hence there is no way to complete input of a line.

I suspect that the keyboard definitions / BIOS are incomplete. The lack of filetransfer facilities and the non-working editor render the system 'an interesting curiosity'

I have tried both TeraTerm and Putty as the terminal emulator both fail to be recognised by the editor.

Is a memory map available for the UCSD implementation for the Z80-MBC2?

Thanks

There was mention along the way of a 128 kbyte implementation of the UCSD P system. Where do I find it?

Thanks
