/* * DEC 93 Erik Bos * * Copyright 1996 Marcus Meissner * * Mar 31, 1999. Ove Kåven * - Implemented buffers and EnableCommNotification. * * Apr 3, 1999. Lawson Whitney * - Fixed the modem control part of EscapeCommFunction16. * * 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. * * 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. * * August 12, 1997. Take a bash at SetCommEventMask - Lawson Whitney * * July 6, 1998. Fixes and comments by Valentijn Sessink * [V] * 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. * */ #include "config.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 "windef.h" #ifdef HAVE_SYS_MODEM_H # include #endif #ifdef HAVE_SYS_STRTIO_H # include #endif #include "heap.h" #include "options.h" #include "server.h" #include "winerror.h" #include "services.h" #include "callback.h" #include "file.h" #include "debugtools.h" DEFAULT_DEBUG_CHANNEL(comm); #ifndef TIOCINQ #define TIOCINQ FIONREAD #endif /* window's semi documented modem status register */ #define COMM_MSR_OFFSET 35 #define MSR_CTS 0x10 #define MSR_DSR 0x20 #define MSR_RI 0x40 #define MSR_RLSD 0x80 #define MSR_MASK (MSR_CTS|MSR_DSR|MSR_RI|MSR_RLSD) #define FLAG_LPT 0x80 #ifdef linux #define CMSPAR 0x40000000 /* stick parity */ #endif #define MAX_PORTS 9 struct DosDeviceStruct { char *devicename; /* /dev/cua1 */ int fd; int suspended; int unget,xmit; int baudrate; int evtchar; /* events */ int commerror, eventmask; /* buffers */ char *inbuf,*outbuf; unsigned ibuf_size,ibuf_head,ibuf_tail; unsigned obuf_size,obuf_head,obuf_tail; /* notifications */ int wnd, n_read, n_write; HANDLE s_read, s_write; }; static struct DosDeviceStruct COM[MAX_PORTS]; static struct DosDeviceStruct LPT[MAX_PORTS]; /* pointers to unknown(==undocumented) comm structure */ static LPCVOID *unknown[MAX_PORTS]; /* save terminal states */ static struct termios m_stat[MAX_PORTS]; /* update window's semi documented modem status register */ /* see knowledge base Q101417 */ static void COMM_MSRUpdate( UCHAR * pMsr, unsigned int mstat) { UCHAR tmpmsr=0; if(mstat & TIOCM_CTS) tmpmsr |= MSR_CTS; if(mstat & TIOCM_DSR) tmpmsr |= MSR_DSR; if(mstat & TIOCM_RI) tmpmsr |= MSR_RI; if(mstat & TIOCM_CAR) tmpmsr |= MSR_RLSD; *pMsr = (*pMsr & ~MSR_MASK) | tmpmsr; } void COMM_Init(void) { int x; char option[10], temp[256], *btemp; struct stat st; for (x=0; x!=MAX_PORTS; x++) { strcpy(option,"COMx"); option[3] = '1' + x; option[4] = '\0'; PROFILE_GetWineIniString( "serialports", option, "*", temp, sizeof(temp) ); if (!strcmp(temp, "*") || *temp == '\0') COM[x].devicename = NULL; else { btemp = strchr(temp,','); if (btemp != NULL) { *btemp++ = '\0'; COM[x].baudrate = atoi(btemp); } else { COM[x].baudrate = -1; } stat(temp, &st); if (!S_ISCHR(st.st_mode)) WARN("Can't use `%s' as %s !\n", temp, option); else if ((COM[x].devicename = malloc(strlen(temp)+1)) == NULL) WARN("Can't malloc for device info!\n"); else { COM[x].fd = 0; strcpy(COM[x].devicename, temp); } TRACE("%s = %s\n", option, COM[x].devicename); } strcpy(option, "LPTx"); option[3] = '1' + x; option[4] = '\0'; PROFILE_GetWineIniString( "parallelports", option, "*", temp, sizeof(temp) ); if (!strcmp(temp, "*") || *temp == '\0') LPT[x].devicename = NULL; else { stat(temp, &st); if (!S_ISCHR(st.st_mode)) WARN("Can't use `%s' as %s !\n", temp, option); else if ((LPT[x].devicename = malloc(strlen(temp)+1)) == NULL) WARN("Can't malloc for device info!\n"); else { LPT[x].fd = 0; strcpy(LPT[x].devicename, temp); } TRACE("%s = %s\n", option, LPT[x].devicename); } } } static struct DosDeviceStruct *GetDeviceStruct(int fd) { if ((fd&0x7F)<=MAX_PORTS) { if (!(fd&FLAG_LPT)) { if (COM[fd].fd) return &COM[fd]; } else { fd &= 0x7f; if (LPT[fd].fd) return &LPT[fd]; } } return NULL; } static int GetCommPort_fd(int fd) { int x; for (x=0; xibuf_tail > ptr->ibuf_head) ? ptr->ibuf_size : 0) + ptr->ibuf_head - ptr->ibuf_tail; } static unsigned comm_outbuf(struct DosDeviceStruct *ptr) { return ((ptr->obuf_tail > ptr->obuf_head) ? ptr->obuf_size : 0) + ptr->obuf_head - ptr->obuf_tail; } 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); } static void CALLBACK comm_notification( ULONG_PTR private ) { struct DosDeviceStruct *ptr = (struct DosDeviceStruct *)private; int prev, bleft, len; WORD mask = 0; int cid = GetCommPort_fd(ptr->fd); TRACE("async notification\n"); /* read data from comm port */ prev = comm_inbuf(ptr); do { bleft = ((ptr->ibuf_tail > ptr->ibuf_head) ?
