* ==== == ======
|
|
* 6/10/96 kipo created it
|
|
* 6/22/96 kipo close com port when disconnected; allow checking for
|
|
* valid TAPI lines during NewComPort().
|
|
* 7/08/96 kipo added support for new dialogs
|
|
* 8/10/96 kipo added support for dialing location
|
|
* 1/06/97 kipo updated for objects
|
|
* 1/24/97 kipo bug #5400: Compaq Presario was overwriting the dev caps
|
|
* buffer, causing a crash. Fixed to allocated a larger
|
|
* buffer with some slop as a workaround.
|
|
* 3/04/97 kipo close com port handle when deallocating call; use string
|
|
* table for modem strings; updated debug output.
|
|
* 3/24/97 kipo added support for specifying which modem to use
|
|
* 4/08/97 kipo added support for separate modem and serial baud rates
|
|
* 5/07/97 kipo added support for modem choice list
|
|
* 5/23/97 kipo added support return status codes
|
|
* 4/21/98 a-peterz #22920 Handle LINE_CLOSE message
|
|
* 5/07/98 a-peterz #15251 Track call errors in DPDIAL
|
|
* 10/13/99 johnkan #413516 - Mismatch between modem dialog selection and TAPI device ID

/* Bug #5400 -
|
|
|
|
My trusty Compaq Presario returns two line devices. The second device says it
|
|
needs 555 bytes for dev caps, but when you give it a pointer to a 555-byte block
|
|
it actually writes 559 (!) bytes into the buffer! Whoah, Bessy!
|
|
|
|
This makes Windows very unhappy in strange and magical ways.
|
|
|
|
The fix is to start with a very large buffer (1024 bytes?) like all the samples do
|
|
and then leave some slop in subsequent reallocs, which should hopefully clean up
|
|
after these messy critters.
