| Issue |
To execute the command of TTY_CMD or TTY_ARGV seems on TTY_PSEUDO and the FILL_COLOR and TERM_FONT are completly ignored.
Could you provide us with more info about this?

| Solution |
The TTY_CMD/TTY_ARGV and TTY_PSEUDO are order-dependant. You have to set TTY_PSEUDO before setting TTY_CMD/TTY_ARGV.
The FILL_COLOR defines the color of the margins. This fact is mentioned in the docs. The background color of the terminal defaults to black or wathever your TERM_COLOR_TABLE resource defines as entry #0.
Unless you know what will be running in the PtTty, it is not a good idea to change black into something completly different by setting TERM_COLOR_TABLE. It is better to set the background color by sending appropriate escape sequences to the terminal. The safest way is to call PtTerminalPut() function before you set TTY_CMD/TTY_ARGV. Escape sequences accepted by PtTerminal are listed in the docs for Dev.con/Dev.ansi. |
