Subject: Turbo's AUX: device

When using CP/M Turbo Pascal to access a modem in slot #2 on an Apple,
input and output is done via the AUX: device (rdr: and pun:).  A simple
program to dial out on a Smartmodem would be:
 
        program dial_out;
        begin
           writeln(aux,'ATDT 555-1212')
        end.
 
This works fine on a CCS-7710 serial card, but NOT on the Videx PSIO card.
The only difference in the serial cards is the CCS uses a 6850 UART, while
the PSIO uses a 6551.  This appears to be a discrepancy with Turbo, as
both cards work fine with MEX and MODEM7.  Any comments?
