[Coco] Hayes modem "+++" timing question

[Allen Huffman]

I have coded up a Hayes command parser for my Ethernet experiment. Much to my surprise, the Hayes "AT" command set seems to be alive and well -- even in modern cellular/hotspot type modems. There is a Wikipedia article on "Hayes modem AT commands" that I found interesting.

My question for today:

On a Hayes smartmodem, typing "+++" will enter command mode (with a 1 second pause before and after, configurable).

Does anyone know if there is a timeout during the wait period for the "+++" string? i.e., this works:

(1 sec pause)+++(1 sec pause)

...and certainly works even if you type the "+++" slowly. But is there a timeout/reset between looking for the "+" characters? Will this work:

(1 sec pause)++(5 sec pause)+(1 sec pause)

Or...

(1 sec pause)++(60 sec pause)+(1 sec pause)

I would think there would be a reset timeout, but I have yet to find any docs online that mention one.

Thanks,
