Note
Some programs that emulate an ASCII terminal do not properly
support the basic ASCII command functions shown in Table 2– 16.
Ampro provides a suitable PC terminal emulator program, TVTERM,
on the Common Utilities diskette.
After booting this system, the keyboard and screen of the serial terminal become the system
console. Note that the programs you execute via the serial terminal must use ROM BIOS video
functions (rather than direct screen addressing) for their display I/O.
Note
DOS programs that write directly to video RAM will not display
properly on a serial console device.
Using a Standard PC Keyboard
If you hav e both a se rial terminal and a standard ke yboard attached to you r system at th e same
time, both keyboards will function.
Using Arrow Keys During Setup
During Setup, the serial console arrow keys and function keys must be simulated.
The arrow keys are simulate d with the su bstitute ke ystroke s show n in Table 2- 17.
Table 2– 17. Arrow Key Substitutions
Function
Substitute Keys Up ^ or Ctrl e
Down v or Ctrl x
Right > or Ctrl d
Left < or Ctrl s
PgUp Ctrl r
PgDn Ctrl c
To simulate the fun ction ke ys, en ter two key strokes, an “F” f ollow ed by the f unctio n key numbe r.
Thus, function key F3 is simulated with the literal “F3” typed on the key board. ( Don ’t type the
quotes). F10 is simulated with “F0”.
Note that these keystroke simulations are only valid during Setup, not during normal operation.
COM Port Table
When the sy stem bo ots und er D OS, the se rial ports are initialized to 9600 baud (typical) . To
preserve the selected console port parameters stored in Setup, the Ampro ROM BIOS deletes the
selected console port from the internal COM port table, normally used by DOS to locate the serial
