SC114 - minimum - unable to send CPM-A_SCM_CF_Format_code8000.hex

[Ronald Maas]

Hi,

I've got SC114 with an SC145 Compact flash module.

The CF card is detected :

Small Computer Monitor - RC/Z80
*devices
Supported devices:
  = Z80 SIO (rc)     @ 80
  = Z80 SIO          @ 80
  = Z80 SIO (rc)     @ 84
  = Z80 SIO          @ 84
  = Z80 CTC          @ 88
  = Z80 CTC          @ 8C
  = ACIA             @ 80
  = ACIA             @ 40
  = Bit-bang serial  @ 28  detected
  = CF Card          @ 10  detected
  = Diagnostic LEDs  @ 00  detected
  = Status LED       @ 08  detected
Console devices:
1 = Bit-bang serial  @ 28

I select SEND FILES from the minicom menu (ESC S) but whichever transfer method I choose no file is being sent. It flashes up with file being sent, but nothing has been transferred and g 8000 to run the sent program hangs the system.

Any pointers or things to look at?

I've tried 2 different FDTI cards, both with the same results.

Settings in minicom for the serial port:

Hi Ronald

I'm not familiar with minicom but in general you should select hardware flow control and send the SCM App as a raw text file without any additional delays or software flow control bytes.
This is described here: https://smallcomputercentral.com/scm-apps/scm-apps-loading-instructions/

If I'm interpreting your minicom settings correctly you should probably turn off software flow control.

If the SEND to SC114 completes correctly you should see "Ready" displayed on the terminal.
