Hola Roderick!
 RR> Here's the problem..  Using the following code on my system (which
 RR> only has a plain old 14.4k modem on COM2), output works--i.e. I type
 RR> ATH1 and the phone goes off-hook--but I don't get any input from the
 RR> modem (i.e. I don't see the ATH1 and the subsequent OK).
 RR> Note, If I skip the "SetComAddress", and just use "OPEN COM2:..." both
 RR> input and output work beautifully..
 RR> Ideas anyone?
 Yes, when you change de port base address with SetComAddress you change only 
this, the COM port base address. PowerBASIC expects that COM1 uses IRQ 4. You 
can use COM1 for base ports COM1 and COM3, and COM2 for COM2 and COM4 that 
use IRQ 3.
 In the other hand, you can use the IR parameter in PowerBASIC Open COM 
statement, like this:
 RR> Here is the code:
 RR> $lib com
 RR> $include "extcomm.inc"
 RR> $link "extcomm.pbl"
 [...]
 RR> open "com1:38400,N,8,1" as #1 len = 1024
     Open "COM1:38400,N,8,1,IR3" as #1 len=1024
 [...]
 With this little modification the code works fine.
 Remenber that you must known what IRQ is assigned for each COM port. 
ually:
 COM1 and COM3 = IRQ 4
 COM2 and COM4 = IRQ 3
 But this behaviour may change if the system has more that 2 serial ports.
