Pointer to this struct is usually able to be a register variable, so access is no worse than any stack variable (all register-relative). Kinda kludgey, but the original ZModem code design depended on lots of globals, and I didn't want to redesign the whole damn thing. Besides, it's more efficient than constantly pushing & popping args all over the place. */ struct Vars { struct XPR_IO io; /* Copy of XProtocol IO struct passed in by term prog. */ struct XPR_UPDATE __aligned xpru; /* Scratchpad xpr_update() control struct */ struct timeval __aligned Starttime; /* Time transfer started */ UBYTE __aligned Rxhdr[4]; /* Received header */ UBYTE Txhdr[4]; /* Transmitted header */ UBYTE Msgbuf[128]; /* Scratchpad buffer for printing messages */ UBYTE Filename[PATHLEN]; /* Name of the file being up/downloaded */ UBYTE Pktbuf[KSIZE]; /* File data packet buffer */ UBYTE Modembuf[256]; /* Input buffer for data from modem */ UBYTE Outbuf[KSIZE*2+256]; /* Output buffer for data to modem */ UBYTE *Modemchar; /* Next char to get from Modembuf */ UBYTE *Filebuf; /* File I/O buffer address */ UBYTE *Filebufptr; /* Current position within Filebuf */ void *File; /* Handle of file being transferred */ long Oldstatus; /* Original terminal program's modem settings */ long Baud; /* BPS setting of modem */ long Strtpos; /* Starting byte position of transfer */ long Fsize; /* Size of file being transferred */ long Rxbytes; /* Number of bytes received so far */ long Filebufpos; /* File offset of data in Filebuf */ long Filebufmax; /* Size of Filebuf */ long Filebuflen; /* Number of bytes currently stored in Filebuf */ long Filebufcnt; /* Number of bytes remaining/written in Filebuf */ long Rxpos; /* Received file position */ long Txpos; /* Transmitted file position */ short Filcnt; /* Number of files opened for transmission */ short Errcnt; /* Number of files unreadable */ short Noroom; /* Flags 'insufficient disk space' errors */ short Rxbuflen; /* Largest frame they're willing to xfer */ short Tframlen; /* Largest frame we're willing to xfer */ short Rxtimeout; /* Tenths of seconds to wait for something */ short Tryzhdrtype; /* Header type to send corresponding to Last rx close */ short Modemcount; /* Number of bytes available in Modembuf */ short Outbuflen; /* Number of bytes currently stored in Outbuf */ short Rxframeind; /* ZBIN or ZHEX; type of frame received */ short Rxtype; /* Type of header received */ short Rxcount; /* Count of data bytes received */ short Znulls; /* Number of nulls to send at beginning of ZDATA hdr */ short ErrorLimit; /* How many sequential errors before abort */ char Rxbinary; /* Force binary mode download? */ char Rxascii; /* Force text mode download? */ char Thisbinary; /* Receive this file in binary mode? */ char Lzconv; /* Suggested binary/text mode for uploads */ char Eofseen; /* Text-mode EOF marker (^Z) received on download? */ UBYTE Zconv; /* ZMODEM file conversion request */ UBYTE Zmanag; /* ZMODEM file management request */ UBYTE Ztrans; /* ZMODEM file transport request */ UBYTE Lastsent; /* Last text char written by putsec() */ UBYTE Lastzsent; /* Last char sent by zsendline() */ UBYTE Fileflush; /* Flush file I/O buffer before closing? */ UBYTE Attn[ZATTNLEN+1]; /* Attention string rx sends to tx on err */ }; /* Option settings and other variables needed outside of XProtocolSend/Receive; separated from rest of Vars so that huge Vars struct doesn't have to be allocated except during transfers.
