Digi One Sp problem with a 56k modem

Realport
1

Hello all
I have a problem with a Digi One SP and a 56k modem.

This is my previus configuration:
server -> serial cable -> 56k modem -> PSTN <- 56k modem <- time recorder

The new configuration is:
virtual server -> lan switch -> Digi One SP -> serial cable -> 56k modem -> PSTN <- 56k modem <- time recorder

I have installed in the virtual server the Realport driver and I can make a call with the modem, but an error occurs in the data exchange!

I have setup the Digi one SP with this parameters:
Serial Settings:
Baud Rate: 9600
Data Bits: 8
Parity: None
Stop Bits: 1
Flow Control: Software

Can anyone help me?
There is a chance to see the transaction log of the DIGI ONE SP ??

I have used the portmon.exe utility to see the traffic log and i see this error

IRP_MJ_WRITE -> TIMEOUT

this is a partial log:
