I have collected several responses to my short note about the new packet layout, and would like to pass them along to others. Thanks to all who supplied comments. I have not had time to formulate any responses to these suggestions. 73, Hank

Hi Hank. It would be nice if you were to increase the size of the packet somewhat, if only to compensate for the additional overhead. My reason is somewhat selfish, but I'm sure that it would be important to other CP/M people: CP/M uses 128 byte records. When sending COM files, it would be nice to be able to receive a record at a time, simplifying programming and allowing some of the hookups (like mine) to work without too much crap. Can the TNC handle it? How about just jacking it up to 256 bytes instead of 128, just to keep it power of two and allow for any new stuff we may do later, especially with weird routing codes or whatever. Anyway, just a thought. If you get this before you leave on your vacation, how about dropping a note re next packet meeting?

Talk to you later, Rick

Hi Hank, John here ...

Just saw your message about new versions of LIP/TIP and repeater. Two brief recommendations: first, a TIP feature which would have a bit table and/or a user settable timeout for packet transmission triggerings. The command --( would begin the list of delimiters ; thereafter each typed character would have a bits turned on in the' table of delimiters. --) would exit this mode. Thereeater whenever a character was keyed which had its bit on in this table, a packet would be sent. (This is the general case, user settable version of your KA6M** tests for colon, etc.) A third command such as ~-' would clear the bit table - The timeout would be specified with a set of digits (followed by any nondigit) after a --t command (as in "--t50 " to set the timeout to 50 tenths of a second). If any character has been keyed but no packet has been sent in that much time, the packet is sent on as-is. This is' the perferred delimiter method for computer output since it tends to come out in bursts, but with no fixed delimiters. Setting the timeout to zero would disable it. Note that the keyed characters can only be edited locally before the
