Continued debugging of the 1053 Emulator - part 4

EMULATOR PLUGGED INTO THE 1130 AND TESTING RESUMES

I put the emulator through its paces, printing every character on the typeball and issuing every movement command - space, backspace, tab, line feed, and carrier return/line feed. I checked that the column displayed on the box matched where the typewriter would be. 

I wanted to verify that the box turned on the +TWR END OF LINE signal when it reached the right margin. This included changing the right margin and verifying that the behavior changed. The typewriter should issue bell characters each time it prints past the right margin. Further, when that signal is asserted, the typewriter should stay busy and automatically perform a carrier return and line feed.

The end of line signal did not work properly. I need to debug this further on the next session. As far as printing speed goes, the emulator did perform at about 16 characters per second if they are all on the same hemisphere. Where I ran into speed problems was in the performance of a carrier return and again with a tab. These took way too long to calculate the new column or complete the return operation. I need to work on the code in the Arduino to fix these speed issues. 

I used the space button to reach certain columns where I used the Tab Set and Tab Clear buttons then verified via the TABS = command typed over the serial link that the proper tabs were there. I used the tab command and the tab button to verify that the emulator reached those points, both in the column number and in the position on the screen of the remote terminal.

I issued Shift to Red and Shift to Black commands, to check that the characters 'printed' on the terminal were in the appropriate color. The ANSI Colors commands are being issued by the box and the terminal program running remotely should be honoring those as it displays the output that would have appeared on the paper if the 1053 were being used instead of the emulator. 

The colors did NOT change. I suspect this is an issue with the configuration of the Putty terminal program rather than a defect in the emulator. I will debug this further on the next session. 

Otherwise the emulator seemed to be performing properly. Once I address the issues I discovered with colors, the end of line signal and the performance doing tab or return, I will repeat the testing to finish this box off.
