Hello together,
the restoration of my PDP-8 and TU56 going forward. Many PDP 8 machine
tests are OK. The TU56 come slowly back to life.
My current problem is, that i do not own a ASR33. Or is it no Problem?
I testet the M8655 with the echo and printer test like in the smal
computers handbook described. All is working fine. I see readable
characters in cutecom on my linux desktop. With the cutecom i also send
the binloader and the testprograms to the PDP8. There i have no problems
too. But... some maindec testsoftware is doing printouts on the Teletype
witch i canot read on cutecom. Exactly the same happens, if i bootstrap
software witch come on tape with the tapedrive.
Exampe hexdump of the output from software on tape (generated with
cutecom):
00000000: 00 ff bf b0 b0 ae b0 b0 20 c0 20 b1 b1 ae b3 b0
00000010: 20 8d 8a aa aa c7 8d 8a 8d 8a 8d 8a 8d 8a c4 c5
00000020: c3 d4 c1 d0 c5 a0 d3 d9 d3 d4 c5 cd a0 c4 d4 a3
00000030: b4 8d 8a 8d 8a c2 c9 ce c1 d2 d9 a0 cd cf ce c9
Is there an existing software witch can act like a ASR33 for typing and
printing , or i got to write my own ?
Many thanks to all who help me again and again.....

The terminal program needs to be configured for 7-bits with MARK parity
and 1 STOP bit to be compatible with a ASR33.
See URL below for a long discussion:

I don't know about cutecom, but Tera Term and putty both support
MARK parity. Some terminal programs don't.
