There is lot of work todo on the sourcecode. must rename lots of the labels. The sourcecode assembles on ISIS-II Emulation, the hexfiles are verified with the original contents of the eprom.

For a TTY terminal communication I would use Linux, configuring the serial port in grub bootloader (like console=ttyS0,9600n8).
you can try HTerm, it is absolutely possible that the software is causing the problems in sending data.
mentioned sawtooth on RX, depending on type of transceiver-IC a level of 10-20% are normal due to +/-15V generation by step-up converter.
Notes:
1.
When I first tried the programmer, it quickly got quite hot but seemed to work.
But upon trying to read a EPROM always got the 3-beep error signal and a – in the Display.
Chapter 2-2-2 explains this as a Logic Level Error Message.
Opening the device, I found 2x 10u unnamed tantalum (next to C5/C6) were short circuit.
After replacing them, the device stays cool and reading ROM works.
2.
If the serial cable is not built according to Appendix A8, the Programmers starts to beep as soon as in Comm- or CPU-Mode.
See Chapter 4-6-2 DSR Signal
3.
Serial immediately works with 8n2 in Putty, but Putty can not send files…
(Maybe copy-paste will work, if XON/OFF is used)
Serial works with YAT terminal Program, but sending files at 4800 fails
withoult flow-control, it works at 2400 baud.
To get clean data on P command, YAT needs the advanced option set to hide NULL-bytes.
TODO: Check if 4800bd works with XON/OFF, i only found out after the scan of the manual that it seems to be supported…
