I think my original request maybe bit misinterpreted. Let me explain again: We have mobile Phone Reference Board, on which we are running Android Framework with Linux Kernel 2.6.29 underneath. Now we want to dump Trace Data Coming From Cellular modem (again part of mobile Phone Reference Board) to PC over USB Port. We intend to use USB ACM (g_serial) class to achieve the same, but we are not sure what through putwe can achieve on our Board. so we want to do through put measurement of Data received from Mobile Phone Reference Board to PC over USB (using g_serial class). Does anybody know if any free Tool/utility exist to do such kind of measurement on Linux/Windows PC. PS: Currently we don't plan to buy such tool commercially, and this is just needed for internal evaluation purpose.

The simplest would be to pv /dev/zero >/dev/ttyUSB0 or pv </dev/ttyUSB0 >/dev/null (replace ttyUSB0 with ttyACM0 if you are on device side). Maybe that helps. -- Best regards, _ _ | Humble Liege of Serenely Enlightened Majesty of o' \,=./ `o | Computer Science, Michał "mina86" Nazarewicz (o o) +----[mina86*mina86.com]---[mina86*jabber.org]----ooO--(_)--Ooo-- ��.n��������+%������w��{.n�����{���)�� jg��� �����ݢj����G���� ���j:+v���w�m������w�������h�����٥
