W8SDZ@Simtel20.ARPA@sri-unix.UUCP (09/17/84)
From: Keith Petersen <W8SDZ@Simtel20.ARPA> Frank Wancho has released a new version of MODEM (302) for TOPS-20. It is now available from SIMTEL20: Filename Type Bytes CRC Directory MICRO:<CPM.TOPS-20> MODEM.EXE.302 ASCII 20480 825FH MODEM.MAC.302 ASCII 48121 5A5BH This version has ALL of the timeout and error recovery features of MDM730 as modified by PAT730V8. There are 27 changes detailed at the front of the source file. All previously known bugs are fixed in this version. One new bug has been introduced and remains to be found and fixed: in batch receive mode (with respect to the mainframe end), the first sector of each file transfered is NAK'd. This does NOT occur in single-file receive mode and thus remains a mystery. Frank considered this minor and decided not to hold up this release until he found it. A reminder for TAC users: unless your TAC port's input buffer has been set to 134 characters instead of the default 64, there is no hope of ever being able to upload at speeds higher than 300 bps. If you don't know the setting of your port, check with your TAC Liaison as listed by the NIC WHOIS program for TACname-TAC. Also, it is strongly recommended that you give your TAC the following three commands before attempting to open a connection: @D C A @F O E @F I E Since it appears that it is possible to have flow control exerted by the TAC even while in binary mode, you must shut that feature off to have any hope of transferring files at any speed. (You must do this sequence even if you are starting a new connection with your TAC as the person(s) before your may have left either or both of those features on. They are NOT reset by an @R or @L or hangup.) Bug reports and whatnot concerning this new version of MODEM to WANCHO@SIMTEL20. --Keith
