gtpm1m2w | TPF V4R1 Migration Guide: 3.1 to 4.1 |
To use binary synchronous communication (BSC) support in the TPF 4.1
system, you need to make the following changes:
- Use the number of messages on the input list (rather than the core block
levels) to set the shutdown and restart levels for BSC processing.
Specify these levels on the BSDWN and BSRES parameters of the SIP CCPPOL
macro.
- Use 3745 partitioned emulator processor (PEP) generation, with the
following parameters.
- LNCTL=BSC
- BSC group definition.
- CLOCKING=EXT
- Modems use external clock.
- SPEED=2400
- Bits for each second.
- DUPLEX=HALF
- Half duplex (1D) lines.
- CU=2703
- Simulate 2703 transmission control.
- MODEM=OPTION2
- Host must enable lines.
- NEWSYNC=NO
- Do not send New-Sync to modem.
- TYPE=EP
- All lines always operation in emulation program (EP) mode.
- Code the following parameters for each BSC line.
- ADDRESS=(xxx, yyy-z)
- Where:
- xxx
- Is the port.
- yyy
- Is the subchannel.
- z
- Is the channel adapater address.
- TADDR=chars
- Is needed for the tributary line only where:
- chars
- Is the polling character.
- Define the high and low subchannels used by the EP support using channel
adapter GROUP definitions.
