|
|---|
| 5 | * It doesn't access a "termcap" file. Instead, it uses an initialized array
|
|---|
| 6 | * of strings to store the entries. Any string that doesn't start with a ':'
|
|---|
| 7 | * is taken to be the name of a type of terminal. Any string that does start
|
|---|
| 8 | * with a ':' is interpretted as the list of fields describing all of the
|
|---|
| 9 | * terminal types that precede it.
|
|---|
| 10 | *
|
|---|
| 11 | * Note: since these are C strings, you can't use special sequences like
|
|---|
| 12 | * ^M or \E in the fields; your C compiler won't understand them. Also,
|
|---|
| 13 | * at run time there is no way to tell the difference between ':' and '\072'
|
|---|
| 14 | * so I sure hope your terminal definition doesn't require a ':' character.
|
|---|
| 15 | *
|
|---|
| 16 | * getenv(TERM) on VMS checks the SET TERM device setting. To implement
|
|---|
| 17 | * non-standard terminals set the logical ELVIS_TERM in VMS. (jdc)
|
|---|
| 18 | *
|
|---|
| 19 | * Other possible terminal types are...
|
|---|
| 20 | * TERM_WYSE925 - "wyse925", a Wyse 50 terminal emulating Televideo 925
|
|---|
| 21 | * ... or you could set $TERMCAP to the terminal's description string, which
|
|---|
| 22 | * $TERM set up to match it.
|
|---|
| 23 | *
|
|---|
| 24 | * Note that you can include several terminal types at the same time. Elvis
|
|---|
| 25 | * chooses which entry to use at runtime, based primarily on the value of $TERM.
