The method used is ; simply to try a read without stall on the remote's line, echo to ; the user's terminal if there was data, read without stall on the ; users local terminal and send that data to the remote if there was ; data to be read. If neither terminal had data to get, then Kermit ; will suspend itself for 1 second. For RT11, we will never stall. ; Also, for RT11, whenever we get 20 (8) characters, we will send ; the remote system an XOFF so we can catch up on the input due to ; the RT MT service overhead for single character i/o. chcount = 0 exectyp = 2 needxon = 4 locsize = 10 dort11: dorsts: sub #locsiz ,sp ; allocate local r/w data mov sp ,r4 ; and a pointer to it please clr -(sp) ; allocate single character buffer mov sp ,r3 ; and point to it please call getsys ; get system type movb r0 ,exectyp(r4) ; save system type in exectype(r4) mov #10 ,chcount(r4) ; count down for rt11 to do an XOFF clr needxon(r4) ; don't need to send xon yet calls noecho ,<#ttname> ; don't want echoing please calls gttnam ,<#ttcons> ; get the 11's terminal name calls ttyini ,<#ttcons,#lun.co,#locmod> tst r0 ; did it work bne 5$ ; no, exit with error calls ttysav ,<#ttcons> ; save terminal settings calls ttyset ,<#ttcons> ; set terminal up tst r0 ; did the initialization work ? bne 5$ ; no, exit calls ttyini ,<#ttname,#lun.ti,#remmod> tst r0 ; did the initialization work ? bne 5$ ; no, exit calls ttyset ,<#ttname> ; ok, set some useful things up br 10$ 5$: jmp 90$ 10$: .iif ne,r$rt11 ,call contrp ; special ^C things for RT11 20$: clr r2 ; assume a short nap is needed calls xbinrea ,<#lun.ti,#-1> ; try to get a charater from remote call errchk ; insure error is correct one tst r0 ; did it work ? bne 30$ ; no, send an XON to the remote system clrpar r1 ; yes, drop any aprity bits please movb r1 ,@r3 ; yes, get the character and print cmpb r1 ,#'S&37 ; /48/ Xoff? beq 24$ ; /48/ Yes, ignore calls binwri ,<r3,#1,#lun.co>; it out on the local terminal 24$: call dumplo ; dump to a log file perhaps mov sp ,r2 ; and say we don't want to sleep dec chcount(r4) ; is it time to do a RT11 XOFF ? bne 40$ ; no, wait a while then cmpb exectype(r4),#sy$rt ; if not rt11, then skip the xoff bne 25$ mov #2 ,needxon(r4) ; will need to send xon later call sxoff ; yes, send an xoff please 25$: mov #10 ,chcount(r4) ; and reset the character counter br 40$ ; and look for local terminal input 30$: cmpb exectype(r4),#sy$rt ; if not rt, then skip the xon bne 40$ ; not rt tst needxon(r4) ; really send an xon today? beq 40$ ; no dec needxon(r4) ; don't overdo sending xon's please call sxon ; no data, send an xon please 40$: calls xbinrea ,<#lun.co,#-1> ; see if any input is pending from tst r0 ; the local terminal bne 70$ ; no movb r1 ,@r3 ; yes, get it and send it to the bic #^C177 ,r1 ; insure no high bits are set. cmpb r1 ,conesc ; other system unless it's the escape bne 50$ calls xbinrea ,<#lun.co,#20> ; char. get the next one please tst r0 ; but wait for it. did it work ? bne 70$ ; no bic #^C177 ,r1 ; insure no high bits are set. cmpb r1 ,conesc ; really send the escape ? beq 50$ ; yes call concmd ; yes, do the command tst r0 ; exit ? bne 100$ ; yes, bye br 70$ ; no, next please 50$: setpar @r3 ,@r3 ; insure correct outgoing parity now calls binwri ,<r3,#1,#lun.ti>; the data is for the remote system tst duplex ; full or half duplex connection? beq 60$ ; full calls binwri ,<r3,#1,#lun.co>; half, send it back please 60$: mov sp ,r2 ; flag that no wait is needed 70$: tst r2 ; should we take a short nap ? bne 80$ ; no cmpb exectype(r4),#sy$rt ; don't wait if rt11 beq 80$ ; yep, it's rt11 today calls suspend ,<#1,#0> ; yes, sleep 1 second for RSTS/E 80$: jmp 20$ ; and back for more 90$: direrr r0 ; problems in getting the connection 100$: tst (sp)+ ; pop the one byte buffer and exit calls ttyfin ,<#ttcons,#lun.co> calls ttyrst ,<#ttcons> ; restore terminal settings calls ttyfin ,<#ttname,#lun.ti> .iif ne,r$rt11 ,call conrst ; for RT11 control C junk add #locsiz ,sp ; pop local r/w data return ; bye .sbttl RSX Connect code - Rev. Notes ; ; This is the terminal emulator for Kermit-11 on native RSX. It was ; rewritten because the original version developed on the RSTS emulator ; was unsuitable for native RSX. It wouldn't work reliably at baud ; rates over 1200 on a moderately busy system. ; ; ; Bob Denny 10-Mar-84 ; ; NOTE: vt125's are a problem as they don't send xon when you type one ; ; John Pieper 840607 fix for connecting to an autocall modem ; Note: Autocall modems are a pain under RSX. ; If the TTnn: is set /remote , ; the Terminal Handler will NOT let you talk to it until it senses ; DSR . This logic is based on the assumption that a remote line ; will be used only for incoming calls. ; If the TTnn: is set /noremote , ; then you can talk to it, but the Terminal Handler will drop DTR . ; Thus, unless your modem has a local DTR override, it thinks ; that you are not connected to it. ; Solution: RSX-11m V4.1 allows TC.DLU = 2 ; which holds DTR but allows you to talk without having DSR . ; Note -- this mechanism is NOT available from MCR level. ; Further, TC.DLU must be reset to 1 when KERMIT is done or else ; the system will not recognize the TT as really being remote -- ; things such as .IFF <LOCAL> in an indirect command file will fail. ; ; John Pieper 840614 Slave Terminal Fix! ; Due to a change in the Terminal Handler, a slaved terminal must also ; be attached or else unsolicited input will NOT be kept in the ; typeahead buffer.
