Bob-
<<It has MAXFRAME = 1 which
means that each packet has to be acknowledged
one ack per line at a time in a connected mode.
Normal packet MAXFRAME can be as high as 7 >>

In the fine print of the D7 brochure Kenwood say:
"Built-in 1200/9600bps TNC (1 packet, 1 frame, 256 bytes)
compliant with AX.25 protocol* " and the asterisk only seems to relate to mode
selection not requiring a PC.



I may be the only one who bought a Kenwood with no understanding that this
1-1-256 limit was different from what "real" TNCs do but I suspect a lot of the
Tasco modem arguments center around this little fact.

Does teh AX.25 protocol say anything about these limits? Or, is it just that
everything [sic] but APRS presumes rhe hardware will be more capable?
