I had the same problem. Try adding the lines:

ModemSendFillOrder:     LSB2MSB
ModemRecvFillOrder:     MSB2LSB         # opposite of earlier models

to the end of your config.tty* file.  I found this worked on some MT5634ZDX
modems (which did class 2 even though customer support said they didn't).

The 56K modems appear to use a Rockwell chipset and one of our customers
had problems with them and went back to the MT2834ZDX (The MT2834ZDXb-u
appears to have the same chipset)

Here's a sample config file for the MT5634ZDX modems:

#
# Configuration for a Multi-Tech MT5634ZDX modems, also sometimes sold as
# MT2834ZDXbu
#
# CONFIG: CLASS2: LT*33*6*MT5634ZDX
#
# BEGIN-SERVER
# END-SERVER
#
# Modem-related stuff: should reflect modem command interface
# and hardware connection/cabling (e.g. flow control).
#
ModemType:              Class2          # use class 2 interface
ModemRate:              38400           # lock rate for DCE-DTE communication
ModemFlowControl:       xonxoff         # default
#
ModemNoFlowCmd:         AT&K
ModemHardFlowCmd:       AT&K3           # hardware flow control
ModemSoftFlowCmd:       AT&K4           # software flow control
ModemSetupDTRCmd:       AT&D3           # setup so DTR drop resets modem
ModemSetupDCDCmd:       AT&C1           # setup so DCD reflects carrier (or not)
ModemSetupAACmd:        AT+FAA=0        # enable adaptive-answer in class 2
#
#
ModemDialCmd:           ATDT%s          # T for tone dialing, @ for silence
#
Class2RecvDataTrigger:  "\022"          # character sent to modem to start recv
ModemSendFillOrder:     LSB2MSB
ModemRecvFillOrder:     MSB2LSB         # opposite of earlier models
