We're migrating all shell logins (and everything else) to the FreeBSD machine, so getting this fixed would be a Very Good Thing. :) I haven't checked to see if other terminal emulations do this. Could this be a 'feature' of the FreeBSD port of pico? -Dave Andersen ----- forwarded message from one of my users ------ I did a raw capture on the data coming down the line to my terminal. It appears that shell is padding the positioning commands in the vt100 emulation with spaces, whereas the terminal emulation from terra is not. In other words, the pico menu at the bottom of the screen on terra is built simply by the appropriate ANSI command strings. There are no space characters sent between the ^G in inverse video and the ^O. It only sends the proper positioning commands. shell, on the other hand, writes out the ^G, then sends a BUNCH of spaces, then outputs the ANSI commands for the next menu item (^O), then more spaces, etc. So, in essence, shell seems to be putting out two to three times more data than terra to write the same screen. Perhaps this is just the vt100 emulation? ----- end forwarded message ------ -- angio@aros.net Complete virtual hosting and business-oriented system administration Internet services.
