[hylafax-users] USR Courier V. Everything Performance

Hello

I appreciated Lee's input on my USR 33.6 External issue, that modem has since returned to the bin in which it was found.

I performed a garbage upgrade and attached a USR Courier V. Everything to hylafax, which has actually managed to receive all pages sent to it so far (still using the 13 page test) from the HP T45xi/deskjet FAX.

My problem now is performance.

With the 56K voice and 33.6 fax modems, I could expect to receive all 13 pages (on occasions when errors were absent) in around 3 minutes.

With the Courier V. configured as a class 1 device, I can expect 13+ minutes to receive all 13 pages.

With the Courier V. configured as a class 2.0 device, I can expect a receive time of just over 5 minutes (still significantly longer than the sportsters).

I have noticed that as a class 1 device, there appears to be some difficulties encountered with HDLC frames/termination, and perhaps this is "fixable".

Here is a typical log from Courier V. configured as a class 1:

A typical class 1 log contains 4300 lines, as opposed to 200 lines in a class 2 log.

Questions:

Is there something that I can do to address the HDLC errors (apart from purchasing another modem) so I can run in class 1?
When in class 1, the remote wants 2-D MMR, but in class 2.0 the same remote wants 1-D MH. Does this account for the 2 minute speed difference between sportster receives and courier class 2.0 receives? Is there anything that would remedy this behavior?

Thank you again for your much appreciated help!
