You are bringing up a good point. Clover and other modes are certainly a good reason to keep them...except that I am strictly a contester and won't use them for anything but RTTY:-)
I brought the pair to K1TTT for this year's WPX and could not see any advantage vs. MMTTY, although we didn't go through the trouble of feeding them with the audio from the Timewave DSP-599zx. For me, it boils down to performance- does it copy any better than MMTTY or not.

I vote to keep them.  I still have my DXP38 and use it quite often for Clover and also Amtor and Pactor ARQ modes.   I guess it all boils down to how much you use them vs. the cost of the USB to serial cable.   I have 2 computers, one is a newer laptop that does not have serial ports, so I run the  DXP38 off the older computer.
I have not made an recent HAL vs.soundcard program comparisons, socannot help you there.   I'd keep them just in case you get the bug to run ARQ modes.. there are still some of us who do.   We usually get on Clover on Sundays on 14065.50 LSB, the old "calling freq" for Clover.

I have a pair of DXP-38 modems that I got a couple of years ago, but never bothered integrating into my station. I no longer have a computer with serial ports and was wondering if the DXP-38 was worth the USB to serial cables. I know it's juts a few bucks, but sometimes less is more, i.e. keep it simple.
So, compared to MMTTY, how well does the HAL play? My thinking was to use it in diversity reception, fronted by a Timewave DSP-599zx in RTTY tone pair regeneration mode or just the data mode filter. This is where the complexity comes into play.
So, keep them pair or sell them? If keep them, shall I bother with the DSP front-end or just feed them with the regular audio from my Icom 756P3s?
Thanks for sharing your thoughts.
