Lawson Whitney * - Fixed the modem control part of EscapeCommFunction16. * * Mar 31, 1999. Ove Kåven * - Implemented buffers and EnableCommNotification. * * Mar 3, 1999. Ove Kåven * - Use port indices instead of unixfds for win16 * - Moved things around (separated win16 and win32 routines) * - Added some hints on how to implement buffers and EnableCommNotification. * * Oktober 98, Rein Klazes [RHK] * A program that wants to monitor the modem status line (RLSD/DCD) may * poll the modem status register in the commMask structure. I update the bit * in GetCommError, waiting for an implementation of communication events. * * July 6, 1998. Fixes and comments by Valentijn Sessink * [V] * * August 12, 1997. Take a bash at SetCommEventMask - Lawson Whitney * * * May 26, 1997. Fixes and comments by Rick Richardson [RER] * - ptr->fd wasn't getting cleared on close. * - GetCommEventMask() and GetCommError() didn't do much of anything. * IMHO, they are still wrong, but they at least implement the RXCHAR * event and return I/O queue sizes, which makes the app I'm interested * in (analog devices EZKIT DSP development system) work. */ #include "config.h" #include "wine/port.h" #include #include #include #include #include #ifdef HAVE_STRINGS_H # include #endif #include #include #include #ifdef HAVE_SYS_FILIO_H # include #endif #include #include #include #ifdef HAVE_SYS_MODEM_H # include #endif #ifdef HAVE_SYS_STRTIO_H # include #endif #include "winbase.h" #include "winerror.h" #include "wine/server.h" #include "async.h" #include "file.h" #include "heap.h" #include "wine/debug.h" #ifdef HAVE_LINUX_SERIAL_H #include #endif WINE_DEFAULT_DEBUG_CHANNEL(comm); /*********************************************************************** * Asynchronous I/O for asynchronous wait requests * */ static DWORD commio_get_async_status (const async_private *ovp); static DWORD commio_get_async_count (const async_private *ovp); static void commio_set_async_status (async_private *ovp, const DWORD status); static void commio_async_cleanup (async_private *ovp); static async_ops commio_async_ops = { commio_get_async_status, /* get_status */ commio_set_async_status, /* set_status */ commio_get_async_count, /* get_count */ NULL, /* call_completion */ commio_async_cleanup /* cleanup */ }; typedef struct async_commio { struct async_private async; LPOVERLAPPED lpOverlapped; char *buffer; } async_commio; static DWORD commio_get_async_status (const struct async_private *ovp) { return ((async_commio*) ovp)->lpOverlapped->Internal; } static void commio_set_async_status (async_private *ovp, const DWORD status) { ((async_commio*) ovp)->lpOverlapped->Internal = status; } static DWORD commio_get_async_count (const struct async_private *ovp) { return 0; } static void commio_async_cleanup (async_private *ovp) { HeapFree(GetProcessHeap(), 0, ovp ); } /***********************************************************************/ #if !defined(TIOCINQ) && defined(FIONREAD) #define TIOCINQ FIONREAD #endif static int COMM_WhackModem(int fd, unsigned int andy, unsigned int orrie) { unsigned int mstat, okay; okay = ioctl(fd, TIOCMGET, &mstat); if (okay) return okay; if (andy) mstat &= andy; mstat |= orrie; return ioctl(fd, TIOCMSET, &mstat); } /*********************************************************************** * COMM_BuildOldCommDCB (Internal) * * Build a DCB using the old style settings string eg: "COMx:96,n,8,1" * We ignore the COM port index, since we can support more than 4 ports. */ BOOL WINAPI COMM_BuildOldCommDCB(LPCSTR device, LPDCB lpdcb) { /* "COM1:96,n,8,1" */ /* 012345 */ char *ptr, temp[256], last; int rate; TRACE("(%s), ptr %p\n", device, lpdcb); if (strncasecmp(device,"COM",3)) return FALSE; if (!*(device+4)) return FALSE; if ((*(device+4) != ':') && (*(device+4) != ' ')) return FALSE; strcpy(temp,device+5); last=temp[strlen(temp)-1]; ptr = strtok(temp, ", "); /* DOS/Windows only compares the first two numbers * and assigns an appropriate baud rate. * You can supply 961324245, it still returns 9600 !
