Does anyone have a modem7-type program for ISIS (the operating system of Intel MDS systems)? We have MDS220's and MDS800's here, which are 8085-based machines. It seems to me that it shouldn't be too much effort to take modem7 (which is in 8080 mnemonics) and modify it to run on ISIS: change the reading and writing of the modem port, and write a subroutine called BDOS which takes the arguments as they would be passed to a CP/M BDOS and makes the appropriate ISIS call. Any pointers and advice (e.g. how to access the modem port) would be appreciated. Thanks in advance.
