Subject: New CPM Version?

With the advent of MEX and Modem7xx and any number of communications
programs. Combined with the neat features of ZCPR it seems it is about
time for a new version of "standard" CP/M, say CP/M 2.3. I suggest we
add some new jumps to the BIOS for communications hardware. Specifically
       MDMIN  - Modem In, read character from modem into A
       MDMOUT - Modem Out, write character in C to Modem
       MDMST  - Modem Status, Returns 0/FF in A is modem is ready to send
                or has recieved a character (C=0 for input status, 1 for
                output status)

Have DRI update the BDOS, (ie fix any bugs) and maybe add some system calls
for accessing the communications port. And voila CP/M 2.3. All in 64K so 
everyone can use it, maybe using banks as a BIOS option.
