ISDN, serial speed, etc.

Hi all,

I use a PowerMac 7600/132 98MRAM with a USR Courier I-Modem (128K ISDN). I
use system 7.6.1 and the PPP that came with the system.

My 2 channels bond when I download a big file, but uploading is very slow
and I never see the 2 channels bond. I'm pretty sure I'm not getting
maximum serial speed on my Mac (115? or 230?).

My questions:

1) how do I find out what is my serial speed and change it to the maximum
possible? Is there freeware/shareware that measures the modem serial port

2) I got a line of code from USR to make the Courier I-Modem bond right
away when I log on (but keep its dunamic behavior!). In other words, to
make the Courier I-modem bring up the second line right away but drop when
I need to use the analog phone. The string is:


This makes it bond when 1% of the 64K channel is used.

Question: where does this string go? What is the file that I need to add
this string to, and exactly where in the file does this line go?

Thanks for your help,
