PET4016 working with WiModem (but stuck at 300baud)
#1
Very cool, I was able to connect to particles BBS and post/read some messages.

On a 40 column Commodore PET 4016 (that was upgraded to 32K).  (5V from the tape connector on the side)

I used PETTERM  (specifically PETTERM40G.PRG since I have the "graphical" keyboard instead of the "business" keyboard).

My only issues is I couldn't change the baud rate of the WiModem successfully.

I did AT*B1200 and it said "OK" and then any typing after that was garbled (so I assume this means the baud rate change took, however the OLED was still showing "300" but it did show a little "AT*B1200" as it shows the last typed command?)

I assumed the change to 1200 would be stored, so I tried just doing a reboot and re-running PETTERM setting at 1200 baud - but still didn't work.  I had reboot again, set back to 300 baud.


After typing "AT*B1200", I'm not aware of any way to change the baud rate once you've passed the startup menu (where you specify the baud rate upfront).  i.e. the PET doesn't have like ALT, CTRL, ESC, etc. to specify a hot-key to change states.   But I'm new to do this, and maybe am just aware of how.

Still, I expected the OLED on the wiModem to change from "300" to "1200" in the corner.  I also tried 2400, same issues.

Maybe the PET 4016 and Commodore BASIC 4.0 isn't able to go past 300 ?

Thanks for making these devices, very cool Big Grin

Oh, and I wasn't sure how to issue a BACKSPACE from PETTERM.  I recall it being CTRL-H - I tried the "<" and left-cursor on the PET keyboard, but still no luck.  Not a huge deal, though my PET keyboard stutters a lot Big Grin
