Any help greatly appreciated. > The ST works nicely as a terminal on a VAX, at least under unix. There is, however, a bug in the VT52 emulator in handling cursor movement in column 80. This makes a screen editor like vi get horribly confused when you are trying to edit files which contain some lines of exactly 80 characters. I would expect that the VMS screen editors would evoke the same problem. I guess you could make up a special '520st' termcap entry, but neither the stock vt52 or H19 entries work correctly. There are also some adjustments in the monochrome monitor you or your friendly local TV repairman can twiddle to adjust the size of the displayed screen. However, they are compromise adjustments - if you expand the screen to the full monitor size, you will start to see some pin cushion effect, see the scan lines, and minor focus differencs from center to corner. On the other hand, you get a more readable text display. A simple 3-wire connection using pins 2,3, and 7 seems to work nicely, and 9600 baud is no problem... -- George Robbins - now working with, uucp: {ihnp4|seismo|caip}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@seismo.css.GOV Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)
