**
|

|
|
** Serial and TCP/IP communication routines for DOS, OS/2 and Win9x/NT.
|
||
|
|
** Tested with: TurboPascal v7.0, (DOS)
|
||
|
|
** VirtualPascal v2.1, (OS/2, Win32)
|
||
|
|
** FreePascal v0.99.12 (DOS, Win32)
|
||
|
|
** Delphi v4.0. (Win32)
|
||
|
|
**
|
||
|
|
** Version : 1.01
|
||
|
|
** Created : 13-Jun-1999
|
||
|
|
** Last update : 28-Jun-2000
|
||
|
|
**
|
||
|
|
** Note: (c)1998 - 2000 by Maarten Bekers. This unit tries to make it easier
|
||
|
|
** to use EleCOM.
|
||
|
|
**
|
||
|
|
** Usage:
|
||
|
|
** Before calling any of these routines, first call Com_StartUp:
|
||
|
|
** Pass the following number to it:
|
||
|
|
** 01 - Use the "modem" communications (OS/2, Win32 or FOSSIL)
|
||
|
|
** 02 - Use the TELNET type (OS/2 or Win32 only).
